Explanation:

A dwarf - planet is defined as a celestial body that is spherical due to its own gravity, orbits the Sun, and has not cleared its orbit of other objects. Having an atmosphere is not a defining characteristic for a dwarf - planet. Also, it must be in a path with other objects as it has not cleared its orbit.

Answer:

The object would have to be spherical, orbit the Sun, and be traveling in a path with other objects.
