SOLAR SYSTEM

Detailed explanation-1: -A large body that meets the other criteria for a planet but has not cleared its neighbourhood is classified as a dwarf planet. This includes Pluto, whose orbit intersects with Neptune’s orbit and shares its orbital neighbourhood with many Kuiper belt objects.

Detailed explanation-2: -According to the International Astronomical Union, which sets definitions for planetary science, a dwarf planet is a celestial body that-orbits the sun, has enough mass to assume a nearly round shape, has not cleared the neighborhood around its orbit and is not a moon.

Detailed explanation-3: -The International Astronomical Union (IAU) defines a dwarf planet as a celestial body in direct orbit of the Sun that is massive enough for its shape to be controlled by gravitation but which has not cleared its orbital region of other objects.

Detailed explanation-4: -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.

Detailed explanation-5: -Definition: According to the definition adopted by the IAU in 2006, a dwarf planet is, “a celestial body orbiting a star that is massive enough to be rounded by its own gravity but has not cleared its neighboring region of planetesimals and is not a satellite.
