      It is a little less than half as strong as it is on the Earth, and a little more than twice as strong as it is on the Moon.

      It’s all to do with the mass and radius of the planet (or Moon). Mars is about as dense as the Earth because it’s made of very similar stuff, but because it is smaller it has less mass in total. Together this means that the gravity there would definitely be enough to stop you floating off into space, but still small enough for you to jump around like the Apollo astronauts did on the Moon!
