Where does the prime meridian pass through?

The prime meridian, which is the line of longitude defined to be 0 degrees, passes through Greenwich, England. It was established during the International Meridian Conference in 1884, where it was decided that the prime meridian would pass through the Royal Observatory in Greenwich. This geographical landmark serves as a reference point for the measurement of time and longitude across the globe. Being the starting point for time zones, it plays a significant role in navigation and mapping.

The other locations mentioned do not serve as the reference line for the prime meridian. North America, Africa, and Australia have their own longitudes but are not associated as the starting point for the global coordinate system represented by the prime meridian.
