I keep thinking of various planetary system configurations, and would like to know: What are the fundamental references based on Monte Carlo long-term simulation of planetary systems' evolution that ...
How can astronomers determine the difference between “hydrostatic equilibruim” and “just happens to be spherical”?
This is relevant for the definition of a dwarf planet. I presume the answer will be, well, if we can tell the mass of the body and guess the material. I don't find this very satisfactory because ...
The planetary discriminant is a measure of how dominant a body is within its region of the solar system. For (true) planets, it is >10000 and for dwarf planets it is <1. See this answer for more ...
Ok, so Pluto is only ~1/13 the mass of the objects in "its orbit". This orbital region extends from 40 AU to 70 AU (semi major axes)- Now, just a minute. 30 AU is all the mass we are considering. Now, ...
