While they are not perfectly smooth spheres, they are close enough to be considered so.
* Sun: The Sun is a giant ball of hot gas, and its gravity pulls all its matter towards its center, resulting in a nearly perfect sphere.

* Planets: All the planets in our solar system are spherical, though some are more flattened than others.
