Abstract

The International Astronomical Union (IAU) defines a dwarf planet as a "an object in orbit around the Sun that is large enough to pull itself into a nearly round shape but has not been able to clear its orbit of debris." Perhaps most remarkably, Pluto may harbor a subsurface ocean of water kept liquid by the decay of radiogenic elements deep beneath the planet's crust. Calling it a planet made sense then, but now it has plenty of company in the outer solar system's Kuiper Belt, where maybe up to 200 dwarf planets reside. [Extracted from the article]
