To put that in perspective:
* Earth's gravity is about 9.81 m/s². This means you would weigh about 3,270 times less on Deimos than you do on Earth.
* The Moon's gravity is about 1.62 m/s². This means you would weigh about 540 times less on Deimos than you do on the Moon.
Because of its low gravity, Deimos is very difficult to land on and explore. A small jump would send you soaring through the sky, and any objects you drop would drift slowly down.
