The Wikipedia lists a gravitational acceleration of 0.003 9 m/s2. I am quite sure this is an estimate or calculation, and has never actually been measured. For comparison, Earth's gravitational acceleration is 9.8 m/s2.

What is Deimos's gravity compared to earth?

Deimos, one of Mars' moons, has a surface gravity of about 0.003 m/s², which is roughly 0.3% of Earth's gravity (approximately 9.81 m/s²). This means that an object weighing 100 kg on Earth would weigh only about 0.3 kg on Deimos. The low gravity is due to Deimos's small size and mass, making it difficult for it to hold onto an atmosphere.
