It is a circle because, the earth is a circle, and the equator stretches all the way around the earth.
The Earth's orbit is very nearly a circle, with the Sun very nearly at the center of the circle. The average distance of the Earth from the Sun ... the radius of the circle ... is 93 million miles.
Force of Gravity is why the earth circles.
The circle of illumination always includes 180 degrees of latitude (and 180 degrees of longitude). Considering latitude . . . whatever amount of latitude falls outside of the circle because of the Earth's so-called "tilt" is made up for by the circle extending the same number of degrees past the pole on the other end. Examples: -- Equinoxes: Illumination from 90 degrees south to 90 degrees north latitude. Total = 180 degrees of latitude. -- June solstice: from 66.5 degrees south, over the north pole, past 90 degrees north, and back down the other side to 66.5 degrees north. Total = 180 degrees of latitude. -- December solstice: fropm 66.5 degrees north, under the south pole, past 90- degrees south, and back up the other side to 66.5 degrees south. Total = 180 degrees of latitudfe.
The arctic circle
The circle of illumination intersects the North Pole on the spring and autumnal equinoxes, March 20 or 21 and September 22 or 23, when the Earth's North and South Poles are not tilted toward or away from the sun, but are both at 90 degrees to the sun's rays. The sun is directly above the equator, and every location on Earth has 12 hours of daylight.
Well, once I looked up "circle of illumination" --(geology) The edge of the sunlit hemisphere, which forms a circular boundary separating the earth into a light half and a dark half. (circle-of-illumination) --I could just *begin* to understand your question, which is still very unclear. Please rephrase it. It just doesn't make sense.
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.
This question doesnt make sense so nobody will be able 2 answer it

Not from one point of illumination.
It is a symbol in some Christian denominations to have a circle inside a square (or sometimes a square inside a circle). This represents the connection between heaven (the circle, which is one eternal round) and earth (the square, with the 'four corners' of the earth). It is very popular in the symbolism of the Church of Jesus Christ of Latter Day Saints (commonly called Mormons). Look at the "related links" below for examples.
It is a circle because, the earth is a circle, and the equator stretches all the way around the earth.
Any circle on the Earth's surface whose center is at the center of the Earth is called a "great circle". Any circle with its center anywhere else is called a "small circle". Spiritually, many consider the kaaba (Mecca) to be the center of the Earth's surface.
YES. A small circle is simply a circle around the earth that does not fly over the direct opposite place on earth that a plane took off from. A great circle goes full circumference of earth, where a small circle does not. Being a circle they both fly in a constant direction.
the earth is a sphere but if you look at it as a 2d shape it is a circle
