This is the "prime meridian" (also known as the Greenwich Meridian for the British observatory on the line).
The meridian exactly halfway around the world from the prime meridian is called the 180th meridian or the antimeridian. This line represents the opposite side of the Earth from the prime meridian and is where the International Date Line is located.
