The earth moves in an elliptical orbit, like all planets do, around a common center of gravity.The sun.The size of the orbit is defined by gravitational pull on the mass of the planet and its speed. there is a point of balance where gravitational force and escape velocity are neutralized. So the planet is constantly "falling" towards the sun and at the same time "escaping" the sun. Most planets orbit in the same plane ie they all orbit the sun around the plane of the sun's equator. Like rings parallel to each other and not like the classic portrayal of the atom with electrons circling the nucleus in orbits at every conceivable angle.

On orbits...
The plane of the earth's orbit is called the ecliptic. Since the earth orbits the sun, the sun is also on the ecliptic. As a result, the sun appears to us to move around the sky on the ecliptic.

Around
with gravity
Does either of those help?

Dude, your question makes no sense.
