Earth is a perfect sphere
Geodesy, also called geodetics, is the scientific discipline that deals with the measurement and representation of Earth, its gravitational field and geodynamic phenomena (polar motion, Earth tides, and crustal motion) in three-dimensional time-varying space. Geodesy is primarily concerned with positioning and the gravity field and geometrical aspects of their temporal variations, although it can also include the study of Earth's magnetic field.

WebJul 8, 2024 · There are no other bodies in the system; the only thing gravitationally acting on the Earth is the Sun. The Sun is a perfect sphere, while the Earth is a spheroid with an equatorial radius of 6371 km and a polar radius of 6356 km. Wikipedia gives this equation for the torque caused by a celestial body's gravity acting on the Earth: Web3 Answers. Normally in the absence of rotation, the natural tenancy of gravity is to pull the Earth together in the shape of a sphere. However the Earth in fact bulges at the equator, and the diameter across the equatorial plane is 42.72 km more than the diameter from pole to pole. This is due to the rotation of the Earth.
