Web8 dec. 2013 · Elliptical orbits are stable, possessing the same amount of total energy over the orbit as circular orbits. This is due, for example, to the fact that when the Earth is closer to the Sun in its elliptical orbit it orbits faster, while when it is further away it orbits slower, averaging to a value equivalent to that of a circular orbit.

Why is the Earth’s Orbit Around the Sun Elliptical?
WebAnswer (1 of 9): No, Earths orbit is not decaying. We formed in this orbit some 4.5 billion years ago, and will still be in this orbit some 4.5 billion years (give or take a million) from now.
