What is an asteroid, comet, dwarf planet with respect to their mass, moment of inertia and dimension?

Ans) Dwarf Planet is lighter,smaller than a planet ( Pluto ).They usually are larger than asteroids. For a planet to be dwarf, it requires to satisfy all the rules of being a planet.(requires to revolve around star, Min dimensions etc).

If considering planet and dwarf planet to recolce around similar star, then planet has higher mass thereforehigher moment ofinertia (consider both as solid spheres)

Asteroids are small as compared to the planets and do not usually revolve around planets.
