Ecliptic coordinates are a celestial coordinate system used to specify the positions of objects in the sky. This system is based on the plane of the Earth's orbit around the Sun, known as the ecliptic. It uses two main parameters: ecliptic longitude, which measures the angle along the ecliptic from a reference point, and ecliptic latitude, which measures the angle above or below the ecliptic plane. This coordinate system is particularly useful for astronomers because it aligns with the apparent motion of the Sun and planets. By using ecliptic coordinates, one can easily track the positions of celestial bodies, such as planets and stars, relative to the Earth's orbit.
