The [[dwarf planet]] '''Pluto''', named for the [[Roman]] [[god]] of the [[Underworld]], was discovered in 1930 by [[American]] [[astronomy|astronomer]] [[Clyde Tombaugh]] several years after its location had been predicted by fellow astronomer [[Percival Lowell]] (although Lowell's prediction was based on inaccurate information from that time).

Although it used to be considered to be a planet, in 2006 the [[International Astronomers Union]] demoted Pluto from the status of a [[planet]] to that of a dwarf planet. Recently there have been efforts to restore Pluto's status as a planet.{{fact}}

Pluto has at least three [[moon]]s, the largest of which is [[Charon]]. (The size of Charon is such that Pluto and Charon are often collectively considered to be a binary system.) Pluto has an elliptical orbit.  When it was considered to be a planet, it was usually the furthest from the sun, but there are times due to its odd orbit when it is closer than [[Neptune]].  Relatively little is known about Pluto. <ref>http://science.jrank.org/pages/5352/Pluto.html</ref>
