|Definition=Angular distance in a great circle of reference reckoned from an accepted origin to the projection of any point on that circle. Longitude on the Earth's surface is measured on the Equator east and west of the meridian of Greenwich and may be expressed either in degrees or in hours, the hour being taken as the equivalent of 15ﾟof longitude. Celestial longitude is measured in the ecliptic eastward from the vernal equinox. The mean longitude of a celestial body moving in an orbit is the longitude that would be attained by a point moving uniformly in the circle of reference at the same average angular velocity as that of the body, with the initial position of the point so taken that its longitude would be the same as that of the body at a certain specified position in its orbit. With a common initial point, the mean longitude of a body will be the same in whatever circle it may be reckoned.
|Definition=Longitude is a measurement of distance on the earth’s surface, east or west of the Greenwich, England (0° Longitude) meridian, expressed in angular measurements of degrees or hours from 180° West (or -180°) to 180° East. Degrees of longitude are imaginary lines drawn 60 minutes apart from North Pole to South Pole around the Earth. Each minute of longitude can be further divided into 60 seconds.

Longitude is a measurement of distance on the earth’s surface, east or west of the Greenwich, England (0° Longitude) meridian, expressed in angular measurements of degrees or hours from 180° West (or -180°) to 180° East. Degrees of longitude are imaginary lines drawn 60 minutes apart from North Pole to South Pole around the Earth. Each minute of longitude can be further divided into 60 seconds.Source
