The Frost Line of the Solar System - Physics Forums
2011年2月25日 · Line Solar Solar system System In summary, the frost line is the distance from the Sun where the radiation from the Sun becomes too dim to make ice sublimate into vapour. This boundary is important because it explains why only terrestrial planets exist inside it.

Astronomy in a Simple Solar System - Physics Forums
2020年11月13日 · If you study the solar system from a heliocentric frame, then the planets orbit the Sun (according to the law of gravitation) and the moons orbit their planets likewise. And this is all very simple. Once you have that model, you can explain the motion of all the other objects in the solar system relative to the Earth.
