What's more, being a gas giant, Jupiter does not have a true surface. Similarly, the Gravity Recovery and Interior Laboratory mission from 2011-2012 consisted of two probes ("Ebb" and "Flow") in polar orbit around the Moon to more precisely determine the gravitational field for future navigational purposes, and to infer information about the Moon's physical makeup. Some people don't know what that means!!! This makes Mercury the smallest and least massive planet in the solar system. Mass does not affect the speed of falling objects, As there is only gravity acting on them. Earth, Neptune, Uranus, Jupiter and Saturn which are 5447. Answer (1 of 5): The gravity of Uranus and Venus is 8.87 m/s^2. When discussing the acceleration of gravity, it was mentioned that the value of g is dependent upon location. $\endgroup$ . .
