The apparent path of the Sun across the celestial sphere during a year is called the ecliptic plane. The prime meridian is a terrestrial reference line used for longitude on Earth. The circumpolar plane is the plane perpendicular to the celestial axis around which the celestial sphere appears to rotate. The celestial equator is the imaginary line on the celestial sphere that is equidistant from the celestial poles and perpendicular to the celestial axis.
