planet
Rounded celestial body
A planet is a large celestial body that orbits a star, is massive enough for gravity to make it roughly spherical, and has cleared other debris from its orbital path.
Our solar system has eight planets: Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, and Neptune.
Pluto was reclassified as a dwarf planet in 2006.
In astrology, planets include the sun and moon, believed to influence human affairs: Mercury is in retrograde.
Informally, What planet are you on? questions someone's grip on reality.
