As of 2014, Pluto has five recognized moons. The largest moon, Charon, was discovered in 1978, followed by the discoveries of Nix and Hydra in 2005, Kerberos in 2011 and Styx in 2012. Pluto may have as many as 10 moons.
Although no one knows exactly what Pluto is made of, most scientists agree that it is between 50 and 70 percent rock, with the remainder being composed of various ices. Pluto’s core is composed of dense rock, while the ices form the larger, but less dense, mantle. The very outer crust of Pluto is co
In 2006, the International Astronomical Union redefined the criteria for what qualifies as a planet, causing Pluto to lose its designation as such. As of 2014, Pluto is considered one of five dwarf planets, with the other original eight planets maintaining their position in the solar system.
Pluto is only slightly over 1400 miles wide, about half the width of the continental United States. From its discovery in 1930 until 2006, Pluto was the ninth planet of the solar system, but in 2006, it was demoted to dwarf planet status.
Pluto has an average radius of 715 miles. The planetary body is 20 percent smaller than Earth and it has a diameter of 1,430 miles.
Pluto has a volume of about 1.53 cubic miles, a radius of 715.2 miles, a surface area of 6.42 million miles and an equatorial circumference of 4,493.7 miles. It is only 0.006 times as voluminous as Earth.
Astrological readings indicate that when the Moon is conjunct with Pluto, those affected by it display intense emotional needs and a deep psychological understanding of others. An individual's natal chart indicates if they are affected by this event.
Pluto does not have a weight, because weight is a force exerted by one gravitational body on another gravitational body. The dwarf planet Pluto has a mass of 1.31 x 10^22 kilograms, and it's weight would depend on the acceleration at the surface of another planet.
The planet Pluto is named after Pluto, the god of the underworld in Greek and Roman mythology. The name was suggested by a young girl, Venetia Burney Phair, in 1930 when she heard the news that a new planet had been discovered in the solar system.
Pluto is believed to contain a layer of water ice underneath another thin layer of frozen nitrogen. In addition, there is speculation that Pluto may contain a water ocean.
