Planets

Planets are celestial bodies located within the Solar System across the Universe. Current definitions by the International Astronomical Union define a planet that is in orbit around the Sun, has sufficient mass for its self-gravity to overcome rigid body forces so that it assumes a hydrostatic equilibirum (nearly round) shape, and has cleared the neighborhood arounds its orbit or within another system.

Generally, until 2006, the Earth's solar system was said to consist of nine planets. However, in 2006, the new definitions resulted in reclassification of Pluto, formerly the smallest planet, as a dwarf planet/minor planet.
