Pluto, which is named for the god of the underworld, is 3.7 billion miles away from the Sun. Many astronomers think Pluto should be labeled as an asteroid rather than a planet. One of the reasons for the bust in rant is its' orbit. All planets circle the Sun in about the same plane, Pluto disobeys this rule a difference of 17 degrees of other orbiting planets. This highly elliptical odd orbit takes it as far as 4,582 billion miles from the Sun and as close as 2,750 billion miles to it.
The greatest distance between two planets in our solar system is the distance between Neptune and Pluto. At their maximum separation the distance is 7,404 billion miles!
A day on Pluto is equal to 6 days, 9 hours and 16 minutes on Earth. This is almost one week. One year on Pluto equals 247.7 Earth years.
When the ratio of moon to planet is considered, the Charon (Pluto's moon)/ Pluto's ratio is the largest. Pluto diameter at 1,800 miles is the smallest for a planet in the solar system.
