The next nearest star to us, Proxima Centauri, has a planet orbiting it designated Proxima Centauri b, which has approximately the same mass of the Earth (5.97 x 124 kg) and approximately 1.2 times the radius of the Earth (1.2= 7.56 x 10ā¶ m).
What is the approximate acceleration due to gravity on Proxima Centauri b?
