I agree that the moon will pull the earth some but in order to have a close circle revolution the two bodies in the smaller revolution would have to be very close in size. | |

The two smaller ones orbit the bigger one together, and the smallest one orbits the medium one as well. This is exactly the same setup as the Sun-Earth-Moon system, only the thing in the middle isn't rocky. What are you trying to say when you write "there are not on the same revolution path"? If you mean orbit, then there isn't actually such a thing as a single path Earth follows. It actually gets moved around by the moon constantly, so it isn't a smooth ellipse. | |

Surely, the earth and the moon revolve around the sun together. | |
| Sep 2, 2016 at 19:12 | comment | added | John | I don't think that is true, after making your suggested replacements the animation above would show the sun and the earth with its moon on the same revolution. Additionally it shows the earth with its moon on the same revolution. Neither of those things are the case in our solar system. The earth revolves around the sun and the moon revolves around the earth there are not on the same revolution path. | |
