🪐 JUMP on other PLANETS 🡆 3D Comparison 

You don't know how much I'm in love this channel now. You always comes up with some interesting things and good presentation. ❤️❤️❤️

@Tonni Cruz the landing wouldn’t be that hard because your weight is so much less on Phobos. Hopefully your legs would not break

@Tonni Cruz I had that though also. 🤔 Would the velocity going back to the ground be too much for our bodies to handle?

Me ha gustado mucho el vídeo 👍

@@theoldchannel3450 ​ They did. The difference between the gravity of Mercury and Mars is so small that they're practically identical, as is the difference between the gravity of Venus/Saturn/Uranus.

Imagine jumping on a trampoline on Phobos

@@First-Name--Last-Name *Goodbye forever*

i think it will go to 1-2km 😂

They'll have to come with a disclaimer: "Warning - serious risk of launching yourself into outer space."

@@First-Name--Last-Name yeet

Nope

773 metere not even space it's like a hill

Saitama jumped from the moon to earth, but I am gonna jump from Phobos to Earth. Less go

@@masterblaster3653 773 metere is not a hill. Its probably a small mountain

@@masterblaster3653 almost higher height than tallest building (idk how to pronounce it in typing)

On that second point, does atmosphere effect that at all?

@@Ethan5I5 You're correct to assume any atmosphere would affect you (through drag) and it would affect you on the way up (robbing you of momentum) so you wouldn't reach your 'perfect' height, and you would also feel drag on the way down which would slow you slightly, but you would still hit with the almost exactly the same force as you propelled yourself with. That said, none of these small bodies have enough gravity to hold onto any appreciable atmosphere (the amount of gas present is so small it is referred to as an 'exosphere' and is essentially better than most vacuums we can pull on Earth in labs. So for Earth, with 'One Atmosphere' (1 atm) I can only jump a few tens of cms but I hit with the same force ... atmospheric drag is next to zero. On the Moon (1/6 g) I would do better but the Moon has an exosphere so any drag is zero. On Mars (1/3 g), with only 0.01 atm the drag would be 1% of Earths atmosphere so can be ignored. The small moons like Miranda or asteroids, there is zero atmosphere. On Titan there is 1/8 g yet it's atm pressure is about one and a half times that of Earths so here you could really feel some drag going up and down for the metre or so you could jump but it wouldn't rob you of much impact energy, a few percent say?. As an aside, with the low g and higher atm, you could probably fly with some suitable strap-on wings under your own power. For Jupiter though, if you were jumping on a floating platform at the top of the clouds you would feel more gravity and the pressure would be similar to Earths so for few cms you could jump you would land so quickly drag wouldn't affect you. Your question would be very important a consideration if you were jumping in a liquid but that would require Venus... it's surface pressure is over 90 atm (similar g to Earth) and the CO2 in this hot crushing atmosphere is a supercritical fluid so it acts similar to a liquid... ish. It would be roughly 10 percent the bouyancy of water so you would feel an effect but wouldn't be able to float or swim down there. Sorry for the long answer.

I can confirm that fighter pilots can take 9-10gs for longer than just a few seconds.

@@evilgrimdudeInteresting. Can you be more specific and offer just how many seconds you mean?

@@markzambelli Of course! I can't give you an exact number, but it all depends on the person and how often they are subjected to high g-forces. Physical fitness, proper breathing technique, and continuous exposure to extreme g-forces all play a role :). I know pilots who can withstand 9 plus for much longer than a few seconds.

1km is the way of orbiting phobos or deimos so rather be on deimos

Too bad he died on his way home.

Planet : who is this guy? 👀

Note: Astronaut died on the way back to his home planet.

@@berserkbattery I think it's a joke but either way, incorrect. Phobos orbits at around 9400 kilometres from Mars and Deimos at around 24 thousand. Even though the average human would reach escape velocity on Phobos by jumping, realistically they would never be able to change their speed relative to Mars so drastically as to go out that far.

That'll be some insane billionaire in the far future.

That's Wowbagger the Infinitely Prolonged's brother's quest: Jump on every body in the universe.

There's nothing funny about that. The only reason people went to moon is to jump there (according to nasa's secret docs).

😂very true. One may not survive the impact on return.

I mean you’re kind of correct. Gravity is related to mass and distance to the center of the object. Density is also related to the distance to the center and mass. But gravity doesn’t depend on density. The reason mercury has similar gravity is because the surface is closer to the center of the planet.

@@nadarith1044 I don’t think “Mars has twice the mass of Mercury” and “Mercury has half the mass of Mars” are different

Mercury essentially being an exposed planetary core

@@locngoduy1571 Not what i meant also now i see the guy already mentioned that, i swear i only saw density being mentioned

@@will3346 So in short: surface gravity doesn't depend on density but because of certain factors it actually does that's essentially what you just said

The lower gravity means slower acceleration downward so it may not hurt that much.

@@speedy01247 The speed lifting off at the moment you leave the ground will be the same though at the moment of impact, since there's no air (and no air resistance) on the moons and dwarf planets. And since one would most likely leave the ground faster than he would at 1G, it'd make a lot of sense that he'll hit the ground faster than normal. One could probably avoid injury by "landing like a cat": keeping everything nice and loose; and locking one's knees and hips would definitely lead to injury (since it's his mass hasn't really changed).

With no air to slow you down, you'd keep accelerating on your way back, so it won't be a soft landing at all.

but that also means you basically float and any small bump makes you stay away from the ground for some seconds

@@speedy01247 oh and yeah it wouldn't hurt at all, you would have the same force experienced on the landing than when you jumped, so while you don't do a very strong jump and then land on the head or something like that, you would be like landing on a cloud (but careful with topography, don't jump down somewhere with a lower height)

Well hallo there :D

Yaa me too!

🤡

Id be worried that I would drift over a bigger drop than I reckoned for. When you can jump 700m up, the littlest angle would send you a couple hundred meters at least horizontally

@@tbonestillz True. I also thought of that. However, I'm not sure that the impact on the ground would be too bad considering that you'll be weighing so much less on a small body and would be falling at a much slower rate considering the low gravitational intensity.

@@chrisbustos1431 Also true. If you could jump 700m, that means a "fall" of 700 meters would only equate a fall of .5 meters on earth. So you could jump 700m and even if you drifted over a 1000m cliff (a total of 1700m down) it would probably only have the effect of a 1m to 2m drop on earth.

Fun fact: even tiny celestial bodies have extremely low-mass atmospheres if you count the gas and dust that comes off and stays around them as they float through space, especially close to a star. Don't know how that would ever help you but it's neat to think about at least!

There isn't a minimum mass for that. To never touch the ground you need to enter orbit, implying it's the horizontal velocity that matters. Of course in the real world, you can have a moon with such low gravity that when jumping you become bound to the main planets gravity. In that case you inherit the horizontal velocity of that moon and orbit the planet instead.

Depends on whether we consider neighboring bodies or not. Metaball assumed human launch speed to be around 3 m/s (based on Energy equivalence equation, mgh=mv^2/2). The equation for escape velocity is v=sqrt(2*G*M/r), where M - body mass, r - distance from the center, G - gravity constant. Now it greatly depends on the density of the body, assuming we jump from the surface. Compared to Earth, Phobos is around 3x less dense, but isnt the least dense known body in our system. A transneptunian object 2002 UX25 has a density of c. 0,82 g/cm^3, and its escape velocity is... Well, 300 m/s. Again, all of that is on a assumption that there is no neighboring body. With it included, we might jump high enough to leave original sphere of influence. That however gets a bit more complicated

@@purpur5 well yes it do depend upon both mass, volume. So of course there are more than 1 factors affecting this. So let us fix some - its ratio i.e. density and assume it's equal to earth's one. Jumping speed is also normal human jumping speed. And also assume there are no nearby objects, no air resistance and that object itself is at rest and not spinning at all. Now what can be its equation? Is it already calculated or we do have to calculate cuz I didn't found out on internet. Aside from that is there any known 'largest' object in this universe nearby us where we can actually escape from its gravity?

@@diogoduarte4097 well if that object isn't spinning and there is nothing around it and if we also fixed it's density then what will be its equation?

@@HHH21 Well then using Earth's density, radius and pluggin formula for volume of a ball (which is good enough here) we get equation of sqrt(3/(8*pi*G*rho))*v=R, where rho is density. Plugging in numbers, we get that for human jump to reach escape velocity, we need a body with diameter of 1709 m at most. Be advised that bodies at that scale aren't exactly round, so there will be points where it's easier and harder to "jump off" due to distance difference.

Youd find yourself dead long before you reach the surface

No. It will BE your most concern...you have to jump out the hell out of the sun before you burn!

Considering how hot my feet would be on the Sun, I think I would be able to jump just a little bit without really trying.

Well if that's the case, I just won't go there. @@pasarmahdi4446

Well I hope there's a basketball court on Phobos...

I hope he doesn't replicate the part where he melts in the sun

More evolved? Doubt

In a thousand years, humans then will still look like humans today with very minor difference, just like humans today and humans from a thousand years ago.

I will reincarnate to see

@@enforcerridley158 There won't even be a slight difference. Humans from thousand years ago are completely the same from nowadays.

That last sentence of yours is quite interesting for me, someone whose significant other is named Miranda.

Jupiter, despite being the biggest planet, it's not even close to be the densest planet so its gravity in the surface is not that great but closer to the core, gravity becomes much, much stronger because the core is much denser.

@Peter from NZ lol if you tried to bend your knees on miranda or phobos you'd probably start floating rather than stay on the ground... you'd have to pull yourself to the ground and then jump

Same; I expected jumping on Jupiter would have been impossible.

@@shaun_rambaran I think you can jump with 2.4x times your weight but I could be wrong and I'm not going to try that.

*E*

Duduh-dud-duh duduh duduh

Can I call you Johnny Georgie?

I imagine VR and game engines will allow one to indulge their fantasies.

@@brodriguez11000 that would be cool.

gravity like in phobos would be great you can cosplay superman

I had so many dreams where I can jump and stay afloat for minutes at a time. Weirdly my jump isn't that far from the ground.

I once have a dream like that, it was super fun

@@michaelhamar3305 but you can fly away to outer space

Good luck having a coffee though. Edit: Or urinating for that matter!

You wouldn't be able to run as our legs have evolved based on 1G. You would put one foot forward and wait forever in low G for your weight to shift to it. Look at astronauts trying to get around on the moon. They have to bunny hop to go any faster than a very slow walking pace.

@@NeonVisual excellent point

@@Gavinwad I can imagine a giant centipede being able to do it if it had an upward slope at the end of its run to kind of ramp off ... (Never thought I'd hear myself say those words when I woke up today)

Not so much the mass, but the velocity. For example, on Phobos the escape velocity is 25 MPH. If you could jump with that much speed you wouldn't just go into orbit, but would completely leave the moon and probably crash on Mars!

@@NeonVisual Exactly, somewhat similar to being in water on Earth

Escape velocity: Am I a joke to you?

@BradynLee thanks bradyn. I needed the recap

Its not enough. Make the calculations.

@@RelentlessBROfficial Yes, but thinking that the lack of atmosphere and the extremly low gravity isn't pushing back as they do in Earth, a jump should be way more powerful than in Earth. Anyway I've changed it to something calculated and in theory, right.

No, you won’t achieve escape velocity on Phobos. You will return.

imagine everyone in the sky that would be annoying

You wouldn't be ON Phobos for very long though.

That’s more likely to happen on Miranda

If you replace a gravity of Phobos to gravity of Earth, that will make much fun... Or maybe..

as you can see in the video phobos you're able to jump off of, and i would reckon deimos is the same

You cannot achieve a stable orbit around that body just by jumping up, as you would need some kind of horizontal boost once you're high up. You can however leave Phobos's sphere of influence and enter a stable orbit around Mars.

MBS says in the pinned comment that you actually wouldn't reach escape velocity on Phobos by jumping.

You can if you long jump, but since you jumped from the surface the lowest point of your orbit will probably also touch the surface.

I believe that is called a stone. 😁

Watch video

Phobos: Am I a joke to you?

@@mateuszjokiel2813 Phobos' escape velocity is 41 km/h. You'd have to jump as fast as a moving car.

Daddy issues?

In the old cartoons by the Fleischer brothers, they thought the jumping looked awkward in animation, so they just had him sort of jump/fly, whichever fit the scene. The comics artists sort of copied that as they kept looking for ever-cooler stunts for him to do. It's rather interesting how much of Superman lore was either accidental or cobbled together. Kryptonite was invented so the actor on the radio show could take a vacation, and they could just have another guy groan in pain for those five episodes.

The hulk too.. was to jump very high as well

Nope

It’s not a nice thing tho 😂😂bec you are literally being thrown to space with no return

🤩

No, you can’t fly away on “the” Phobos…

-Not funny. -That joke was never funny.

@@oilersridersbluejays ok and?

Probably not very fast, since running depends on your traction, which depends partially on your weight. The lighter you are, the worse your traction, so you could be trying to sprint but basically just running in place, kicking up a cloud of dust behind you. Sort of like trying to run underwater. It's why videos of moon landings show the astronauts kind of bouncing around, not walking normally. Because they physically can't walk normally.

What If You Can Jump On Any Star

In honor of the planet's discoverer William Hershel's home country, the moons of Uranus are named in the theme of characters of William Shakespeare. Miranda is a character from The Tempest.

less gravity means you accelerate slower so you take longer to lose speed upwards and gain speed downwards

lol you won't land with more force than with what you jumped off. Even jumping down that cliff is like jumping down a few steps on earth.

@@FilmscoreMetaler But like he said, it'd be easy to become unstable and land on your head. People have been crippled by a half-meter drop onto their heads.

@@stevenscott2136 Yes but you still have your hands and slomo time to react so it won't be too dangerous.
