It takes roughly 365 days, or 1 year, for the Earth to complete its orbit around the Sun. Although it is an elliptical orbit, it is almost circular, so there is only a slight difference between the closest and farthest points from the Sun throughout the orbit. The two-dimensional plane occupied by the Earth's orbit is called the ecliptic.
