Bernie B A body rotates on its axis, but revolves about its primary. The term -- to orbit -- is often used in lieu of revolve. So, in your example, the Earth rotates on its axis every 24 hours and revolves around the Sun in 365 days. In both the helio and the geocentrist's position -- Mars rotates on its axis in about 24h 37m but revolves around the Sun in 687 (Earth) days. In each case, the path of revolution is the body's orbit. In your points 1. and 2. below -- an object (a body) which is 'spinning' refers to rotation, but an object in a circular path refers to an object in its orbit. You should be aware that in the Tychonian view, there are only two (roughly) circular orbits -- the Sun and the Moon. All other bodies follow a path which lack a generally accepted name.

Then he comes up to me and says, "The Earth orbits on an axis every 24 hours, and the Earth rotates around the sun every 365 days." So, I'm looking for the correct usage of the words Rotate, Revolve, Orbit in relation to describing 1. a spinning object 2. an object in a circular path Bernie Paul Deema <paul_deema@xxxxxxxxxxx> wrote: Bernie B 2. How about Orbital Revolution and Axial Rotation? If you explain what you mean by this, I'll attempt to answer.
