To be exactly technical about it, the earth and sun do both revolve, around their "common center of mass".

The common center of mass is the point where the pivot would have to be in order for the sun

and earth to balance on a see-saw.

Since the sun's mass is so much greater than the earth's mass (about 332,000 times as much),

the pivot of the see-saw would be much closer to the sun. In fact, the pivot point is inside

the sun, so it appears as if the earth is just revolving around the sun. But the sun is actually

doing a little wobble of its own, as both bodies revolve around the same point.

By constant I assume you mean a perfect circle.

The earth's path around the sun is not equal because there are many other factors of gravity affecting the earth as you read this.
