The Earth is an irregularly shaped ellipsoid.
Explanation:
Determining the size of the Earth by Eratosthenes
Under the assumption that the Sun is very far away, the ancient Greek geographer Eratosthenes performed an experiment using the differences in the observed angle of the Sun from two different locations to calculate the circumference of the Earth.
While the Earth appears to be round when viewed from the vantage point of space, it is actually closer to an ellipsoid.
