11 Οκτ 2024 · Learn more about Pluto and other dwarf planets, which are defined as objects that orbit the Sun and are nearly round, but that have not been able to clear their orbit of debris. The International Astronomical Union (IAU) has recognized five dwarf planets: Pluto, Ceres, Haumea, Makemake, and Eris.
11 Μαΐ 2015 · Dwarf planets are a lot like regular planets: They both have enough mass and gravity to be nearly round - unlike odd-shaped asteroids. They both travel through space in a path around the Sun.
Dwarf planets like Pluto were defined as objects that orbit the Sun, and are nearly round, but have not been able to clear their orbit of debris. So far, the IAU has only recognized five dwarf planets.
10 Αυγ 2006 · The following is the IAU definition of a dwarf planet, planet as well as a definition of asteroid. A dwarf plane t is a celestial body that (a) is in orbit around the Sun, (b) has sufficient mass for its self-gravity to overcome rigid body forces so that it assumes a hydrostatic equilibrium (nearly round) shape, (c) has not

It’s much like a regular planet—only smaller. A dwarf planet meets two of the three requirements for planethood. To be considered a planet, an object must orbit the Sun and have enough gravity to assume a nearly round shape and attract the smaller objects and dust sharing its orbit.
