Draft:Outline of planets

The following outline is provided as an overview of and topical guide to planets:

What type of thing are planets?
Planets can be described as all of the following:


 * Astronomical objects
 * Gravitationally rounded objects

Types of planets
Planet
 * Planet types by location
 * Planet of the Solar System
 * Inferior planet
 * Superior planet
 * Inner planet
 * Outer planet
 * Exoplanet
 * Planet types by make-up
 * Terrestrial planet
 * Giant planet
 * Gas giant
 * Ice giant

Other

 * Double planet – Two planetary mass objects orbiting each other
 * Mesoplanet – A planet smaller than Mercury but larger than Ceres
 * Minor planet – A celestial body smaller than a planet
 * Planetary-mass object –

Planetary attributes

 * Orbit –
 * Heliocentric orbit – orbit around the barycenter of the Solar System, which is usually located within or very near the surface of the Sun. All planets, comets, and asteroids in the Solar System are in such orbits, as are many artificial probes and pieces of debris. The moons of planets in the Solar System, by contrast, are not in heliocentric orbits as they orbit their respective planet.
 * Planetary habitability – The measure of a planet's ability to sustain life.
