An object in the solar system orbits the Sun and has enough mass that its gravity has pulled it into a spherical shape, but it does not have enough gravity to clear its neighborhood of orbiting debris. This object is classified as:

This object is classified as a dwarf planet

Explanation:

A dwarf planet is an object in orbit around the Sun that is large enough (massive enough) to have its own gravity pull itself into a spherical (or nearly round) shape but it does not have enough gravity to clear its neighborhood of orbiting debris. Generally, a dwarf planet is smaller than Mercury. A dwarf planet may also orbit in a zone thathas many other objects in it.
