- Astronomy. a dwarf planet having an equatorial diameter of about 2,100 miles, a mean distance from the sun of 3.674 billion miles, a period of revolution of 248.53 years, and one known moon, Charon. Based on the definition of a planet devised by the International Astronomical Union in 2006, Pluto, regarded as the ninth and most distant planet in our solar system since its discovery in 1930, was reclassified as a dwarf planet, a decision that continues to be examined and questioned by some astronomers.
