You probably want to compare the gravity on the moon and on the three planets. Let's assume that you do. Call the gravity of the earth g and let's compare. Moon - 0.1654 g Mercury - 0.38 g Venus - 0.904 g What that all means is that if you weigh 100 pounds on earth, you'll weigh about 16 and 1/2 pounds on the moon, 38 pounds on Mercury, and about 90 and 1/2 pounds on Venus.
