What are two properties of dwarf planets?

Spherical in shape and has not cleared the neighborhood of its orbit

As per the International Astronomical Union, a   dwarf planet is an object that is definitely not a satellite, is circular fit as a fiddle and has not cleared the area of its circle. At the point when a question "clears its neighborhood," that implies it is never again influenced by the gravity of comparative estimated objects; clearing the area is the main perspective that recognizes predominate planets from standard eight planets.  dwarf planets can have moons and different items caught in their gravity.
