Re: Earth sun moon gravitation
I don't want to go too far off topic but I have a new question to pose about this, semi related to the earth sun moon gravitational attraction question in the OP.
​
If the Sun-Earth gravitational attraction is so much greater than the Earth-Moon, then why doesn't the Sun affect the tides more than the Moon for example? I'm guessing the answer will be distance is closer but isn't that taken into account with the gmm/r^2 equation?

Re: Earth sun moon gravitation
yes, I get it now. Perfect explanation Tazmanius Devilus. Thanks very much. I knew it had something to do with distance, I was just way to tired last night to figure that out on my own.
