What is the ecliptic?
Quick Answer
The ecliptic is the apparent path the Sun follows across the sky over a year. It also marks the plane of Earth’s orbit around the Sun.
The Full Story
The ecliptic is an important concept in astronomy because it is the reference plane for the solar system’s main orbital motion. From Earth, it looks like the Sun travels through a band of constellations during the year. The Moon and planets usually stay near this band because their orbits are close to the same plane. The ecliptic also helps explain why eclipses are relatively rare, since the Moon’s orbit is tilted slightly relative to it.
