Deimos

Deimos is a Martian moon only 13 km in diameter. That means a 44 kg human on Earth will weigh 13.4 g on Deimos! A leap will launch the human into outer space. It is located 23,460 km from Mars. Despite being so small a human on Mars can see Deimos as quite a pale dot in the sky. It looks sort of like Venus seen from Earth.
