==Parameters for classification as a planet==
{{rpl|Jupiter, Florida}}
Jupiter is classified as a planet by the International Astronomical Union for meeting the following criteria:<ref>[http://www.nasa.gov/vision/universe/solarsystem/planetsf-20060824.html Honey, I Shrunk the Solar System] NASA. “The International Astronomical Union has decided that, to be called a planet, an object must have three traits. It must orbit the sun, be massive enough that its own gravity pulls it into a nearly round shape, and be dominant enough to clear away objects in its neighborhood.”</ref>
*Orbits the sun;
*Has mass sufficient for its gravity to form a nearly round shape;
*Has mass sufficient for gravity to clear a path in its orbit.
 
==Physical characteristics==
Jupiter is a little more than five times further away from the Sun than Earth (5.2 AU) and is the most massive of the planets with a total mass of about 318 times that of Earth (318 Earth masses) Its total mass is about 2.5 times all the other planets combined. It is composed largely of [[hydrogen]] and [[helium]].  Jupiter's strong internal heat creates a number of semi-permanent features in its atmosphere, such as cloud bands and the [[Great Red Spot]]. 
 
==Rotational characteristics==
Jupiter has a rotational period (a complete rotation on its axis) of 9.842 hours and a polar tilt of 3°.<ref name=NMMOrbits>[http://www.nmm.ac.uk/server/show/conWebDoc.393 The orbits of the planets] National Maritime Museum</ref>
 
==Orbital characteristics==
Jupiter has an orbital period (sidereal year) of 11.68 earth years. At is closest approach to the Sun (perihelion) it is nearly 5 times the distance of the Earth from the Sun (4.95 AU). At its furthest distance from the Sun (aphelion) it is 5.45 AU from the Sun.<ref name=NMMOrbits/>
 
==Natural satellites==
Jupiter has sixty-three satellites.  The four largest, [[Ganymede (moon)|Ganymede]], [[Callisto (moon)|Callisto]], [[Io (moon)|Io]], and [[Europa (moon)|Europa]] show similarities to the terrestrial planets, such as volcanism and internal heating.<ref>{{cite web|title= Geology of the Icy Galilean Satellites: A Framework for Compositional Studies|author=Pappalardo, R T|work=Brown University|year=1999|url=http://www.agu.org/cgi-bin/SFgate/SFgate?&listenv=table&multiple=1&range=1&directget=1&application=fm99&database=%2Fdata%2Fepubs%2Fwais%2Findexes%2Ffm99%2Ffm99&maxhits=200&=%22P11C-10%22|accessdate= 2006-01-16 }}</ref> Ganymede, the largest satellite in the Solar System, is larger than Mercury.
