Longitude[muokkaa]

Longitudes on Venus are measured eastward from its prime meridian. The original prime meridian passed through the radar-bright spot at the center of the oval feature Eve, located south of Alpha Regio.[1] After the Venera missions were completed, the prime meridian was redefined to pass through the central peak in the crater Ariadne.[2][3]
