**bobpursley**, Tuesday, April 22, 2008 at 4:00pmall elliptical orbits have two focus loci. The Center of Earth is NOT a foci of Earths orbit, as the Earth is always moving. Foci do not travel in orbit. Neither is the Sun at a foci, but very near to it. Other planets pull on the Sun, so it moves slightly in time.

Use the eccentricity to find it.
