Question

Does the moon have hemispheres?

Answer 1

Moon is more like a lemon than a sphere. It has bulge in the sides. The halves about its equator can be called hemispheroids.

Explanation:

Earth is an oblate spheroid and so is the Moon.
Spheroid is an ellipsoid with two of the three axes equal.
At the formation stage, the tidal forces from the Earth and the Sun might have created the bulge along the equator.
