This graphic shows how fast a rocket must go to leave every planet
Gravity makes it possible for us to live on Earth, but it also makes it pretty hard to leave. Satellites fight gravity by going just fast enough to free-fall around the planet indefinitely, like the International Space Station, with many traveling at speeds of more than 17,500 mph.
But if you want to leave this planet, you have to go faster. This speed is called the escape velocity.
And because other planets in our solar system have different gravitational strength, they each have different escape velocities.

Look at that Jupiter rocket go!
ReplyDeleteFascinating information! The velocities on the graphic obviously aren't to scale, since the earth rocket is barely moving faster than the mercury one, which should be going at about 1/3 the speed.
ReplyDeleteBlasting off from Venus would be made much more difficult because of the very dense atmosphere (90x that of earth). The escape velocity may be roughly the same as on earth, but it's probably impossible to attain.
Adamantine bones required for Jupiter. I don't believe we have the technology (yet...) for proper Jupiter exploration, even robots
ReplyDeleteCool, but I thought Mars escape velocity was half that of Earth...
