The old professor says: The Earth, which is very slightly flattened at the poles, is considered to be an oblate spheroid.

Oblate spheroid. When thought of as not perfectly spherical, the Earth used to be described as 'pear-shaped' because it was bottom bulging because there is more water in the southern hemisphere that is more pronouncedly affected by its rotational force. And of course the poles flatten, accordingly. But the pear-shaped analogy was disposed of because it gave the impression that the earth looked like a Bartlett pear.

Earth is more of egg-shaped, it's not perfectly circular. When something is very close of being circular but it's not, it is called elliptical. All planets are elliptical and so are their orbits.

A sphere, but the earth is not a perfect one. It is more oval/egg shaped.

Technically it's known as an oblate spheroid.
