Well, I was wondering about the Earth. Well, I would like to know if
the Earth is really not round, but elliptical as some say.
The Earth is not quite spherical, due to what is know as "rotational
flattening." It's not egg-shaped, either, it's shaped more like a pumpkin. The
radius of the Earth at the equator is 6,378 km; at the poles it is 6,356 km.
Jupiter, which rotates once every 10 hours, is even much squashed than the
Earth. Jupiter's equatorial radius is
70,850 km; it's polar radius is 66,550 km.
