What does spheroid mean?
A three-dimensional shape that approximates a sphere, but is not perfectly spherical. A spheroid can be either oblate (flattened at the poles) or prolate (elongated at the poles).
Example
"The planet Mercury is an oblate spheroid, meaning it is slightly flattened at the poles."
