Answer #6

For a planet to be officially called a planet, it needs to be in orbit around the Sun. It needs to have enough gravity to pull itself into a sherical shape and it needs to have “cleared the neighborhood” of its orbit.

Pluto fulfilled two of the conditions but it didn’t fulfil the last condition. Any object that didn’t fulfil the third condition would be known as a “dwarf planet”.
