The prime meridian of Mars was established in 1971 [35] and passes through the center of the crater Airy-0, although it is fixed by the longitude of the Viking 1 lander, which is defined to be 47.95137°W.

Ultimately the outcome was as follows: there would be only one prime meridian, the prime meridian was to cross and pass at Greenwich (which was the 0°), there would be two longitude direction up to 180° (east being plus and west being minus), there will be a universal day, and the day begins at the mean midnight of the initial meridian.

For a location not on this axis, there is a unique meridian plane in this axial-pencil through that location. The intersection of this plane with Earth's surface defines two geographical meridians (either one east and one west of the prime meridian , or else the prime meridian itself and its anti-meridian), and the intersection of the plane ...
Indians believed that the prime meridian passes through ujjain and calculated their longitudes from Ceylon. The Arabs adopted this idea of Ceylon's being the cupola of the earth but later mistakenly believed ujjain to be the cupola. [22]
