Why do we weigh more on Earth than on the moon?
... another? There are two factors that determine gravitational force. The first is an object’s mass. An object with a large amount of mass will exert more gravitational force than an object with a small amount of mass. Since Earth has more mass than the moon—about six times as much—it exerts more gravi ...

If one star is much fainter than the other, you may not see its lines. The object is then a single-line spectroscopic binary. If both sets of lines are se ...
