The Best Space Facts Had Me Staring at the Night Sky for Hours

gravity is what keeps your feet firmly planted on the ground that's why the average person can only jump about one and a half feet straight up but if we had to live on another planet say venus or saturn let's find out what difficulties we'd have to endure there we'll try mercury first as it's closest to the sun the gravity on this planet is less than half that on earth so you'll be able to jump about four feet high that is if you can stand the temperatures on the sunny side the heat reaches 800 degrees to be there is like standing neck deep in dark red lava on the slopes of a volcano oh boy night won't bring much respite either scorching air will quickly chill to minus 280 degrees you'll also have to be patient since one day on mercury lasts 176 earth days well hopping from this inhospitable place to even less welcoming venus you'd be able to see earth from here if not for the whirling mass of clouds above they create a monstrous greenhouse effect as well as immense atmospheric pressure if you were to jump here you'd make it just shy of 1.7 feet high because the mass and size of earth and venus are almost similar with venus being a little smaller besides the constant temperature of a blazing furnace rain here wouldn't bring relief the clouds up there are made of sulfuric acid skipping our home planet we go straight for its moon luna as it's otherwise called gravity here is less than a fifth of that on earth so if you jump you'll rise almost nine feet in the air and won't touch the ground again for several seconds it's hard to believe this desolate piece of space rock makes tides on earth habit and if you stay on the moon long enough as in a couple million years you'll see how much further it's gone from our home planet next destination is mars the red planet here a vertical jump will take you about four feet in the air if there was any air to speak of of course mars has an atmosphere but it's much thinner than on earth if you stay here until evening you'll be able to marvel at a beautiful blue sunset and you can probably see a mountain from here that's olympus mons the tallest mountain in the solar system it's almost three times taller than everest and it's also a volcano by the way leaping from here to phobos one of the two moons of mars plant your feet firmly and don't be attempted to jump gravity here is so weak that you won't be able to return phobos is really small compared to other modes in the solar system no larger than a big asteroid it's almost a hundred times closer to its planet than our moon to earth eventually it's doomed to be cool critically close to mars and shatter scientists believe mars can obtain its own rings then much like saturn now we're going to a really weird object it's called ceres and it's the largest asteroid in the solar system so large in fact it was later classified as a dwarf planet it's almost exactly halfway between mars and jupiter somewhere in the main asteroid belt if you jump here you'll be taken up almost 52 feet and then slowly fall back ceres is so massive that it accounts for a third of all mass in the asteroid belt fast forward to the next waypoint jupiter being a gas giant this planet has no solid surface so jumping here is irrelevant but if you must you could only hop about 6 inches high jupiter is more than 10 times larger than earth and 300 times as massive so its gravity is enormous there's also a perpetual storm on its surface that's been there for at least four centuries although it's getting smaller with time at the moment our whole planet could fit into that storm our next stop is ganymede the largest of jupiter's moons it's solid so you can easily jump here and make it over 10 feet high this moon is larger than mercury but its mass is significantly lower which makes gravity rather weak ganymede is covered in thick ice and deep beneath that is a liquid metal core this core is why ganymede is the only moon to have a pretty strong magnetic field next we go to saturn the second gas giant of the solar system it's only slightly smaller than jupiter able to fit nine and a half moons in it but way less massive if it had any hard surface to jump from you'd be able to hop as high as 1.4 feet in the air almost as high as on our planet saturn is most famous for its rings which are particles of dust and ice left from impacts with different space objects it spins so fast around its axis that it has flattened itself almost into an oblong shape it also has 62 moons only 5 fewer than jupiter let's explore one of them right now hopping further and here we are on the largest moon of saturn titan jumping here will take you just shy of 11 feet high the atmosphere of this moon is most peculiar it's heavy and mostly consists of nitrogen making the surface appear hazy it's also made almost entirely of ice but there's rock underneath and water is only thought to be deep below near the core and one amazing thing on titan's outside are cryo volcanoes volcanoes that spew ice instead of lava next is the dark and lonely pluto formerly the ninth planet but now no more than a dwarf planet its gravity is somewhat lower than that of triton's and you could jump over 25 feet high here pluto is too small to be a fully fledged planet it's smaller than many moons including ours its atmosphere appears and disappears at times when pluto is closer to the sun the ice on its surface evaporates to become the atmosphere but as soon as it travels further the gas layer goes away so hold your breath let me introduce my spaceship the name of this super fast beauty is the invincible and people won't create anything of the kind for the next several decades the thing is that space distances are seriously long that's why traveling there would take way more time than you'd like to spend on the road for example voyager 1 a space probe launched in 1977 was traveling out of the solar system at the speed of 40 000 miles per hour if my spacecraft moved at the same speed it would take me a whole 77 000 years to get to the nearest star i mean really it would also take me more than a billion years to cross the milky way galaxy but luckily the invincible is much faster than that also i almost forgot to introduce my companion sorry liam you see liam is a robot with a.i you know artificial intelligence that's why i have high hopes for him i'll have someone to talk to during the flight and he can help me if things get really tough and now let the journey begin here we go three two one blast off wow the earth is growing smaller and smaller by the second it seems like no time has passed but our spacecraft is already 200 miles above the surface of our planet since it's daytime i can clearly see the great lakes shining in the sun and oh boy i've just spotted something moving to the left of my ship could it be yes it's the international space station did you know that the station is the most expensive single object in the world ah no wonder with a price tag of 100 billion dollars this money would buy you 250 boeing 747s or two louvres with all the paintings and artwork inside for my spacecraft the iss looks pretty big but i shouldn't be surprised since the length of the station is over 350 feet which is more than the length of a football field but i don't have time to linger a black hole is calling for me now i'm about 1300 miles over the surface of the planet and i start to spot satellites here and there i've read that among satellites there are low and high flyers and while the lowest flying ones move approximately 1250 miles away from earth which is the length of four and a half grand canyons the highest reached 22 000 miles into space which almost equals the earth's circumference measuring about 25 000 miles by the way few people know that satellites travel at a blinding speed from seven thousand to eighteen thousand miles per hour also the higher a satellite is the slower it moves relatively speaking for example the weather tracking goes system of satellites orbits the earth once a day at a distance of 22 000 miles above your head and reaches a maximum speed of 7 000 miles per hour well the satellites are being left behind and my spacecraft has already taken liam and me toward the moon about 240 000 miles away from earth that's the same distance you would go if you went around our planet 10 times in a row from here earth looks like a small bright blue ball hanging in the middle of nowhere and you know what else from my spacecraft i can clearly see that the moon isn't a perfect sphere it's shaped more like uh yeah like an egg wow anyway bye bye moon we're headed somewhere even further hmm i see mars jupiter saturn and neptune passing by in all their glory and look there's pluto who used to be a planet but was later demoted from here earth looks like a small star that's getting fainter and fainter as i'm moving further away [Music] but wait what's that some object is approaching me at a high speed could it be tesla that was close the thing just avoided a collision at the last moment and everything happened too fast to see it clearly but i'm pretty sure what i just saw was a tesla right now i'm already really really far from earth like 100 astronomical units away the thing is that space distances are so vast you can't even calculate them in miles that's why scientists use the term astronomic unit which equals 93 million miles the distance from the sun to earth that means right now i'm 9.3 billion miles away from our planet but what's happening why is my spaceship shaking and rocking so much i see we're entering the termination shock the place where solar winds coming from the sun travel at a speed of 250 miles per second and collide with the material that makes up the galaxy's background ah there we made it through unscathed but there's another trial ahead the orc cloud that means two things first we're on the outskirts of the solar system and second we'll have to get through a cloud of icy objects orbiting the sun at a distance of 100 000 astronomic units in other words it's 1.87 light years away from our star it must be my lucky day since we got through the org clot with just a couple of scratches on the spacecraft's skin and voila we're heading out of the solar system just one tenth of a light year later by the way if you were trying to reach this point by car the trip would take you more than 19 million years and even if you piloted one of the fastest spacecraft that exists nowadays nasa's new horizons you would still need 37 000 years to complete the journey so bring a big lunch all right we've left the borders of the solar system and now i'm sitting in my spaceship cabin watching comets and asteroids pass by time to think about my destination in the center of pretty much every galaxy there's a super massive black hole for example one is sitting right at the heart of our milky way galaxy about 27 000 light years away from earth but even my ship wouldn't be able to get that far before my 100th birthday that's why my destination is the stellar black hole nearest to earth and much smaller in size but no less mysterious it's v616 mondo serratus also known as the 616 mod located 3 000 light years away and weighing the same as about 9 to 13 of our suns a black hole is an eerie place where those laws of physics we studied at school stop working if a massive star runs out of its star fuel it becomes super dense and buckles under its own weight collapsing inward and bringing space time along as a result the gravitational field of this new thing gets so strong that nothing can escape it not even light right now we're approaching the black hole and very soon i'll send liam to explore it from the inside i won't go further than the horizon also known as the point of no return and you can probably guess why right once an object crosses this invisible line it can't turn back even if it changed its mind anyway liam says he's ready to start his journey there he goes bravely plunging toward the black hole while i'm recording everything that's happening to him he's accelerating it looks like he's contorting and stretching as if i'm looking through a huge magnifying glass interestingly the closer to the horizon he is the more slowly he seems to move he's trying to send me encoded light messages like we agreed to in advance but the light wave stretched to redder and lower frequencies i'm okay i'm okay what's happening liam just froze as if a gigantic finger has pressed a pause button and now some force is stretching him thinner and thinner ah i've read about this phenomenon it's the infamous spaghettification which happens in a super strong non-homogenous gravitational field the black hole's gravity force is stronger at his feet than at his head that's why he's getting stretched out like a piece of spaghetti also the sensors inform me that liam is getting hotter and hotter and then nothing he just disappeared and i can't see him anymore but since i did my research before the trip i know that liam is in the state of free fall now and feels no more stretching scalding radiation or gravity unfortunately the connection is lost and he can't tell me anything about the inside of the black hole hmm this is a moment i didn't think through well enough anyway i hope you're okay out there my friend and i think i'll head home to get ready for my next space trip well what's up my name's it and i'm from a planet in a place you call the andromeda galaxy i'm in high school and i have this assignment to find out what will happen to your solar system's perfect harmony if it loses a planet so i poof one of yours away with this ray blaster and track any changes don't worry i'll put them back sort of so let's give it a shot i'll start with the planet closest to the sun mercury right oh it's so small i nearly missed it here we go okay with mercury gone how's earth looking no changes in the solar system i saw that coming it's all about gravity every object that has some mass attracts other objects because of its gravitational force the larger the mass the greater the force it has mercury is the smallest planet in the solar system so it's not too massive in space terms the second most important factor is the distance between the objects at 50 million miles away mercury is no doubt far from earth so the gravitational force between the two of them isn't that strong okay let's put mercury back and move on to venus it's the hottest planet in your solar system one day here is almost 117 earth days i'll try the blue button this time oh do you see that it just froze and broke into pieces and again nothing really changed that much well except you earthling just lost the second brightest object to light up the night sky second to the moon of course i suppose that's why they call venus the evening star looks like it got way darker after sunset than it used to be all right i'll reassemble venus now and head to your home planet earth the one floating rock in the system that's in that precious habitable zone the perfect distance from your star to sustain life hey i was just kidding i'm obviously not gonna poof earth away so let's head to the red planet mars i know humans are planning to send a mission there would you personally want to go tell me about it in the comments below let's see what'll happen when i spin the red planet so fast that it shoots out of the solar system by mars and no significant changes again this might be good for earth in a way there's a massive asteroid belt between mars and jupiter asteroids as you know aren't earth's best friends jupiter holds them together with its strong gravity but from time to time they break free and start moving toward the side no surprise really since its gravitational pull is impressive mars also has gravity to boast and acts somewhat like a slingshot that speeds up asteroids in the direction of earth so no mars no slingshot and the chances of the blue planet getting hit by an asteroid go down ah finally the moment i've been waiting for time to experiment with the largest planet in your solar system jupiter it weighs three times more than all of its neighboring planets combined hmm how am i going to get this giant out of the system i know i'll use the shrink ray and make it two billion times smaller first now i can just throw it like a baseball uh oh i think i made a huge mistake with its massive gravitational force jupiter has protected earth from asteroids and other space debris for the past four and a half billion years now the sun's gravitational pull is sending all that stuff toward the inner planets and that includes earth there will also be some small changes in the orbits of other planets but that would be some thousands of years later for now i gotta figure out a way to get jupiter back before the earth is doomed hmm maybe this button hello okay how about this one ah i'll just push all of them brace for impact whatever it was it worked the giant is now resting peacefully back in its place and earth is saved sorry about that must have given you a real scare i'll try to be more careful with the rest of the gas giants it's time for saturn you can't mistake it for any other planets thanks to those gorgeous rings scientists say they'll disappear one day as saturn's immense gravity pulls them down in an icy rain but that won't be for 300 million years from now so no worries hmm i guess i'll have to push the red button for this one bam and it's gone such a massive planet the second largest in the solar system can't be gone with no consequences look at jupiter and uranus their orbits have slightly shifted other than that i don't see any changes to the other planets saturn is just too far to influence them that's good wouldn't want another close call like what happened when i took jupiter away uranus is massive as well the third largest planet in the solar system i'll try this super powerful space lasso to move it out of the way got it now i'll just throw it out of the system and hmm nothing so far looks like it's the same story as it was with saturn uranus is so far away from the inner four planets that its disappearance has no effect on them whatsoever but i can see that it did mess things up a bit for the outer planets alas we've come to the last planet unless you're on team pluto sorry but i'm gonna go with nasa on its status and exclude it from today's experiment on your happy neighborhood of planets anyway it's neptune's turn beyond it you've got the kuiper belt it's a donut shaped region of icy objects and a ton of dwarf planets like pluto neptune is so close to the outer edge of the solar system then i'll just kick it out wow look at the diaper belt it's going crazy without neptune's gravitational pull keeping things stable orbits are crossing and celestial bodies are crashing into each other check it out pluto's orbit is misshapen now too neptune pretty much controls it as well but it's too far away from earth to affect it in any way i wouldn't want anything to happen to little pluto so let's put the eighth planet back where it belongs but i'm not ready to finish the experiment just yet i need to find something that would really affect life on earth the sun is the obvious answer but the mess and chaos from its disappearance would be too massive and irreversible so i'll leave it where it is what about the moon though i've always had the secret dream to turn it into swiss cheese and bite off a piece it's time oh my what just happened to the earth's axis it's so tilted even more than it was before the weather down there has gone wild too there are no more seasons at all and new ice ages are on the way the ocean tides have become much lower than they used to be and is the planet starting to spin faster yup the day now lasts only 6 to 12 hours because there's no more pull of the moon to slow down the earth's rotation there are also no more lunar or solar eclipses to watch and the knights are so dark with nothing but billions of stars and venus which together are still way dimmer than the moon to light the sky up none of this sounds good for life on earth so i'll de-cheesify your moon and put it back where it was it looks like out of all the planets in your sun's complex system only jupiter's disappearance would be a major problem for earth so i guess it's true what they say the solar system really is a delicate and harmonious balance
