Earth is slightly flatten at the poles and so its shape is described as:
(A) Pentagon
(B) Asteroid
(C) Geoid
(D) Diamond
The Earth is not perfectly spherical. Because it rotates, the Earth is squished at the poles and bulging at the equator, so it is best described as a Greoid. You might have heard the term oblate spheroid, but geoid is the word used to describe the real surface of the Earth, including local irregularities.
Quick Info:Geoid means "Earth-shaped," acknowledging its non-perfectly spherical form.
It is not a polygon (Pentagon/Diamond) or a space rock (Asteroid).
