Tougher question than it sounds. E.g., did you realize that by some definitions Jupiter is a star? (And I’m talking astrophysics, not “well, it’s a point of light, so…”) Under gravational contraction and possibly radioactives in its core, Jupiter emits at a temperature 100 K what it would be at from insolation alone.
Star: Mass of hydrogen, helium, and admixtures of heavier elements powered by nuclear fusion of some sort, with at least some visible light emitted (not reflected). Includes as special cases white dwarfs and neutron stars, which technically don’t meet first half of definition.
Brown dwarf: Composed as with star but does not undergo nuclear fusion. Radiates in infrared from gravitation and radioactives. Shines if at all by reflected light.
Giant planet: Composed as with star but does not radiate measurably. Shines as with brown dwarf.
Terrestrial planet: Composed of rock and/or metal. May also have atmosphere and perhaps hydrosphere if heavy enough. Shines as with brown dwarf. Minimum size: over 1,000 km radius.
Asteroid: Resembles terrestrial planet (but without atmosphere). Maximum size: under 1,000 km radius.
Iceball: Composed of frozen volatiles, possibly with rock/metal admixture.
Under this definition, the Solar System has:
1 star, 1 brown dwarf, 3 giant planets, 4
terrestrial planets, ~1,000 asteroids, and ~100 known iceballs.
