The selenographic colongitude is the longitude of the morning terminator on the Moon, as measured in degrees westward from the prime meridian. The morning terminator forms a half-circle across the Moon where the Sun is just starting to rise. As the Moon continues in its orbit, this line advances in longitude. … See more The selenographic coordinate system is used to refer to locations on the surface of Earth's moon. Any position on the lunar surface can be referenced by specifying two numerical values, which are comparable to the See more Longitude on the Moon is measured both east and west from its prime meridian. When no direction is specified, east is positive and west is negative. Roughly speaking, the Moon's prime meridian lies near the center of the Moon's disc as seen from … See more • Planetary coordinate system • Selenoid See more

Die selenografische Colongitude der Sonne (englisch abgekürzt SSC für Sun's selenographic colongitude) ist die vom Nullmeridian des Mondes in Richtung Mond-Westen von 0° bis 360° gerechnete Position des Schnittpunkts des Terminators des Sonnenaufgangs mit dem Mondäquator, also des Punktes auf dem Mondäquator, an dem gerade die Sonne aufgeht. Die Bedeutung der Colongitude bei der Mondbeobachtung ergibt sich daraus, dass Krater und and… Webn.
