My astronomy teacher has asked me to calculate gravitation pull between Earth and Sun, Earth and Moon, and Sun and Moon. Well, it turned out that gravitational attraction between Sun and Moon ( 4.369 * 10^20 N) is more than twice that of between Earth and Moon (1.986 * 10^20 N). His (and my) question is why doesn't Sun pull Moon toward itself and away from its current orbit around the Earth.
I was thinking that is has something to do with angular momentum or something like that. Should I read more about planet and star creation, to find the answer?
I haven't seen many threads regarding our solor system in the Cosmolgy thread, but if you don't mind can you help me out? Thanks.
