What is the actual geometric shape of earth orbit?

Answer 1

Technically, the true shape of the earth's orbit is an ellipse ... a slightly squashed circle. But if you saw the orbit drawn on paper, you couldn't tell it from a perfect circle. It's eccentricity is 0.017, meaning that the longest dimension of the ellipse is only 1.7 percent longer than the shortest dimension. It looks to you like a perfect circle, and you have to do some fine measuring to detect that it's not.

Answer 2

elliptical

ANS2:The center of mass of the earth and the moon describes an ellipse as the two coupled bodies orbit the sun. Since the mass of the moon is small, its 28-day period of rotation about the earth has only slight effect on the earth's orbit so you are not incorrect in describing the earth's orbit as elliptical since the wobble is only slight. Even describing the orbit of the center of mass of both the earth and the moon as elliptical is really not perfect, either because the other planets perturb the orbit slightly.

Answer 3

The Earth is in the orbit of an oval but similar to a circle.

Answer 4

oblate spheroid is the SHAPE of earth, its orbit shape is an ellipse, a slightly squashed circle-365 degrees so it is not a perfect circle which is 360 degrees

Answer 5

The Earth's orbit is an ellipse.

ALL orbits are ellipses.

Answer 6

The Earth's orbit is an ellipse.

Answer 7

Ellipse

Answer 8

I think it is a sphere
