A '''planet''', as [[2006 definition of planet|most recently defined]] by the [[International Astronomical Union]] (IAU), is a celestial body [[orbit]]ing a [[star]] or [[Stellar evolution#Stellar remnants|stellar remnant]] that is massive enough to be rounded by its own [[gravity]], not massive enough to cause [[thermonuclear fusion]] in its core, and has [[cleared the neighbourhood|cleared its neighbouring region]] of [[planetesimals]].<ref name=IAU>{{ cite web | title = IAU 2006 General Assembly: Result of the IAU Resolution votes | url = http://www.iau2006.org/mirror/www.iau.org/iau0603/index.html | year = 2006 | accessdate = 2007-04-30 }}</ref><ref name=WSGESP>{{ cite web |year = 2001 | title = Working Group on Extrasolar Planets (WGESP) of the International Astronomical Union | work = [[IAU]]| url = http://www.dtm.ciw.edu/boss/definition.html | accessdate = 2006-05-25 }}</ref>

The term ''planet'' is an ancient one, with ties to history, science, myth and religion. The planets were originally seen as a divine presence; as emissaries of the gods. As scientific knowledge improved, the human perception of the planets changed over time, incorporating [[#Former planets|a number of disperate objects]]. Even now there is no unconstested definition of what a planet is. In 2006, the IAU officially adopted a resolution [[2006 definition of planet|defining planets]] within the [[Solar System]]. This definition has been both praised and criticised, and remains disputed by some scientists.
