The term planet is ancient, with ties to history, astrology , science, mythology , and religion. Several planets in the Solar System can be seen with the naked eye. These were regarded by many early cultures as divine, or as emissaries of deities . As scientific knowledge advanced, human perception of the planets changed, incorporating a number of disparate objects. In 2006, the International Astronomical Union (IAU) officially adopted a resolution defining planets within the Solar System. This definition is controversial because it excludes many objects of planetary mass based on where or what they orbit. Although eight of the planetary bodies discovered before 1950 remain "planets" under the modern definition, some celestial bodies, such as Ceres , Pallas , Juno and Vesta (each an object in the solar asteroid belt), and Pluto (the first trans-Neptunian object discovered), that were once considered planets by the scientific community, are no longer viewed as such. |

A planet is generally considered to be a relatively large mass of accreted matter in orbit around a star that is not a star itself. The name comes from the Greek term πλανήτης, planētēs , meaning "wanderer", as ancient astronomers noted how certain lights moved across the sky in relation to the other stars. Based on historical consensus, the International Astronomical Union (IAU) lists nine planets in our solar system . Since the term "planet" has no precise scientific definition, however, many astronomers contest that figure. Some say it should be lowered to eight by removing Pluto from the list, whilst others claim it should be raised to fifteen, twenty, or even higher. |

A planet (from the Greek πλανήτης, planetes or "wanderers") is a body of considerable mass that orbits a star and that produces very little or no energy through nuclear fusion . Prior to the 1990s only nine were known (all of them in our own solar system ); as of 3 November , 2004 , 133 are known, with all of the new discoveries being extrasolar planets , sometimes known as "exoplanets". |

A (major) Planet is a body of considerable mass that doesn't produce light on its own and orbits a star . Until recently, only nine were known (all of them in the Solar system ). As of the middle of 2001 over 60 are known, with all of the new discoveries being extrasolar planets . |
