'''Planet''', '''bintang siarah''', '''kaukab''', atau '''greha''' (bahasa Jawa kuno) adalah [[benda astronomi]] yang [[orbit|mengorbit]] sebuah [[bintang]] atau [[evolusi bintang#Sisa bintang|sisa bintang]] yang cukup besar untuk memiliki [[gravitasi]] sendiri, tidak terlalu besar untuk menciptakan [[fusi termonuklir]], dan telah "[[membersihkan lingkungan|membersihkan]]" daerah sekitar orbitnya yang dipenuhi [[planetesimal]].<ref group="lower-alpha" name="footnoteA">This [[Definition of planet|definition]] is drawn from two separate [[International Astronomical Union|IAU]] declarations; a formal definition agreed by the IAU in 2006, and an informal working definition established by the IAU in 2001/2003 for objects outside of the Solar System. The [[2006 definition of planet|2006 definition]], while official, applies only to the Solar System, while the 2003 definition applies to planets around other stars. The extrasolar planet issue was deemed too complex to resolve at the 2006 IAU conference.</ref><ref name="IAU">{{cite web |title=IAU 2006 General Assembly: Result of the IAU Resolution votes |url=http://www.iau.org/public_press/news/detail/iau0603/ |publisher=International Astronomical Union |year=2006 |accessdate=2009-12-30}}</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=2008-08-23}}</ref>
