- The Earth's orbit around the Sun is very nearly circular, and it defines a plane in space called the ecliptic plane. With respect to the perpendicular to the ecliptic plane (which points to orbital north), the Earth's axis is tilted at an angle of 23.5°: - Change 0 of 0 [|<< First] [|< Previous] [|Next >] [|Last >>] e.
