A scientist discovers a new object in the Kuiper Belt and claims it is a dwarf planet. What would have to be true about the object for the scientist to be correct?

A dwarf planet must orbit the Sun, be massive enough for gravity to make it nearly spherical, and not have cleared other objects from its orbital neighborhood. So the object would be spherical, orbit the Sun, and travel along a path shared with other objects. An atmosphere is not required.
