On the Moon, the escape velocity is: __________?
Correct answer: A. Less than on Earth due to its lower mass and smaller radius
- A. Less than on Earth due to its lower mass and smaller radius
- B. More than on Earth due to its smaller radius
- C. The same as on Earth because escape velocity is a constant
- D. Dependent on the time of day
Explanation
The Moon’s escape velocity is about 2.38 km/s, compared with about 11.2 km/s for Earth. Its much smaller mass more than offsets its smaller radius, making escape easier.

About Astronomy and Space
Astronomy covers the structure and motions of the solar system, planets, satellites, comets, asteroids and meteoroids, together with gravity, eclipses, seasons and phases of the Moon. It also introduces stars, galaxies, nebulae, black holes, space telescopes and satellites, while distinguishing rotation from revolution and meteors from meteorites.
