Question

Earth is not at the center of the moon’s orbit. Describe the exact position of the Earth in the orbit of the moon.

Answer 1

Earth is not at the center of the moon's orbit. Objects in space do not orbit in circles. The orbit in ellipses, or, ovals. Geometrically, an ellipse is formed by two focus points. Much like the sun is at one focus point of the Earth's orbit, the Earth is at one focus point of the moon's orbit.
