Ecliptic

The ecliptic is a term in astronomy that refers to the plane of Earth's orbit. The ecliptic is where most large objects in orbit, around the Sun, lie. The planets are very close to the ecliptic, whereas comets and Kuiper belt objects are frequently at significantly greater angles to it.[17][18] All the planets, and most other objects, orbit the Sun in the same direction that the Sun is rotating (counter-clockwise, as viewed from above Earth's north pole).[19] There are exceptions, such as Halley's Comet.
