Orbicular is an adjective that means having a rounded shape.

The Latin word orbiculus (OR bee coo loose) translates roughly to ‘ball.’ And its descendant, our word of the day may refer to anything rounded in shape. Orbicular is often used by geologists to refer to rocks that are spherical in shape, but the word may be used in more informal contexts. 

As a kid, I always wondered how planets developed their orbicular nature. Now as an astrophysics major, I’m getting closer to an answer.
