Early astronomers called this an "epicycle"; a whirling circle whose center was traveling in a larger circle. They used this to try to explain the observed motions of the planets, because Aristotle said that all motion in the heavens was circular, and so ellipses were right out!

Does the sun circle the earth or does the earth circle the sun?
They both rotate about the center of mass of the Earth Sun System. This center of mass is located inside of the sun but is not the exact center of the sun. As the sun revolves about this point inside itself this causes the sun to wobble slightly. This wobble is how we are able to locate extrasolar planets.
Which force pulls objects in toward the center of a circle?
Centripetal force
What is the shape of an rainbow?
A circle, with a center on the line connecting the sun to your eyes. You only see the top half of the circle because the Earth gets in the way.
Why do we see rainbows only when the sun is relatively low in the sky?
-- The rainbow you see is a part of a circle.-- The center of the circle is on the line from the sun through your head.-- The radius of the circle is 86 degrees.-- The higher in the sky the sun is, the lower underground the center of the circle is,and the less of the circle is above ground where you can see it.===========================================-- Also, in order to see a rainbow, the sun must be in clear sky, whereas there must bewater droplets in the air in the direction where you see any colors. The chances of asetup like this are much better when the sun is low in the sky.

How do you measure circumfrance?

What is the diameter of a circle times pie?
Here are the three circle equations, in words and equations. Circumfwerence - pi X diameter C = pi d Circumference = two X pi X radius C = 2pi r Area = pi X radius squared A = pi r^(2) NB It is only the radial value that is squared ; NOT 'pi'. NB pi is a constant at 3.141592..., usually approximated to 3.14 or 3.1416.
