planet
Meaning
Noun
- Each of the seven major bodies which move relative to the fixed stars in the night sky—the Moon, Mercury, Venus, the Sun, Mars, Jupiter and Saturn.
- A body which orbits a star (or star cluster), is massive enough to be in hydrostatic equilibrium (generally meaning a spheroid) but not enough to attain nuclear fusion and, in IAU usage, dominates the region of its orbit about the star; specifically, in the case of the Solar system, the eight major bodies of Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, and Neptune. (Pluto was considered a planet until it was reclassified as a dwarf planet by the IAU in 2006.)
- Found in phrases such as the planet, this planet to refer to the Earth.
