Hello
Just to throw a small observation into the mix. We know the axial rotation of the earth creates our periods of light and darkness, which we call days. We all know know there is 365 1/4 (averaging leap years and normal years) days in a year. SO how many times does the earth rotate on its axis, in a year? 365 1/4? Nope... 366 1/4!!!
Because the earth also rotates around the sun, even if it did NOT rotate on its axis at all, we would still have one apparent day, one sunrise, and one sunset, by virtue of the earth making this orbit around the sun. Yet because the earth actually does spin on its axis, and this rotation is in the opposite direction to its orbit around the sun, this first axial spin, does, in effect, cancel out this first "orbital day", the first apparent day! SO if the earth only rotated once in a year, the sun would stay in the same place in the sky the entire year, seem FIXED in position, rather than having one sunrise and one sunset, due to the fact the earth rotates in opposition to its orbit.
We know the earth rotates one more time each year than its apparent days. It rotates 366 times in normal years, and 367 times in leap years. This can only be true if the earth both orbits the sun and its spins on its axis. So yes, the earth does orbit the sun, and it does spin on its axis!
