Document Summary
[newton"s law of gravity says that the gravitational force is proportional to. For the 1998 total solar eclipse, i saw it at noon from aruba. The sun is about 400 x farther than the moon. The sun is about 30,000,000 x more massive than the moon. Does the sun or moon exert a bigger gravity force on the. So, on this account only, the solar force would be. But the law of gravity also says that the gravitational force is proportional to the inverse square of the distance. So the solar force should be 4002=160,000 times less than the moon for this aspect. So the sun dominates over the moon (30,000,000x is greater than 160,000x), and that is why the earth orbits around the sun, and not around the moon. ] (2) at that time? . [the time of day is noon, so the sun {and hence the. Moon} are both high above aruba, thus the tides will be high.
