=== Interior ===
Saturn's inside is similar to Jupiter's inside. At the centre is a small rocky core that is about the size of the Earth.<ref name=rgo>{{cite web |url=http://www.oarval.org/section3_11.htm |title=Saturn |work=Information Leaflet No. 42 |publisher=[[Royal Observatory, Greenwich|Royal Greenwich Observatory]] |year=2009 |access-date=April 26, 2011 |archive-date=February 16, 2022 |archive-url=https://web.archive.org/web/20220216154134/http://www.oarval.org/section3_11.htm |url-status=dead }}</ref> Saturn's core is very hot, with [[temperature|temperatures]] reaching 15,000 [[Kelvin|K]] ({{convert|26540|F|C|0|lk=off|abbr=on}}).
