Latitude latitude, to avoid ambiguity with the geodetic latitude and the auxiliary latitudes defined in subsequent sections of this article. Besides the equator, four other parallels are of significance: The plane of the Earth's orbit about the Sun is called the ecliptic, and the plane perpendicular to the rotation axis of the Earth is the equatorial plane. The angle between the ecliptic and the equatorial plane is called variously the axial tilt, the obliquity, or the inclination of the ecliptic, and it is conventionally denoted by . The latitude of the tropical circles is equal to and the latitude of the
Total eclipses on the Moon Total eclipses on the Moon Total solar eclipses on the Moon are caused when the Earth passes in front of the Sun, blocking much its light. Viewers on Earth will see a total lunar eclipse. The last total solar eclipse on the Moon was in July 2018. Unlike the Earth which sees its eclipse for up to 2 1/2 hours the longest in one area as the Moon's shadow touches for over 5 1/2 hours the longest. Some of the eclipses on the Moon lasts for about 5 hours in one area the longest as the Earth's shadow touches for
