Greenwich meridian, an imaginary line, last established in 1851, used to indicate zero degrees longitude. It passes through Greenwich, London, and ends at the North and South poles. Because it indicated zero degrees longitude, it was also known as the prime meridian. It served as the internationally recognized prime meridian from 1884 to 1984 ...
The prime meridian is zero degrees longitude and divides Earth into the Western and Eastern hemispheres. It is also known as the Greenwich Meridian because it passes through Greenwich, a borough of London, and terminates at the North and South poles.
The Prime Meridian is the universally decided zero longitude, an imaginary north/south line which bisects the world into two and begins the universal day. The line starts at the north pole, passes across the Royal Observatory in Greenwich, England, and ends at the south pole.
