How many planets can you walk on?

Answer 1

Of the eight planets in our solar system, four have solid surfaces you could walk on. Those four planets are Mercury, Venus, Earth and Mars. You couldn't walk on Jupiter, Saturn, Uranus, or Neptune because they are made of gases, not solids. Mercury is too close to the sun and Venus is too hot for people to walk on. Everyone who has ever walked has, of course, walked on Earth. Scientists are seriously considering a manned mission to Mars, so that leaves Earth and Mars as the only two planets in the solar system on which you could walk.

Answer 2

As of now, there is only one planet that humans have successfully walked on, which is Earth. However, there are ambitions to walk on other planets in the future, such as Mars.
