what is another name for the prime meridian
Prime meridian A prime meridian is ultimately arbitrary, unlike an equator, which is determined by the axis of rotationâ€”and various conventions have been used or advocated in different regions and throughout history.[1] The most widely used modern meridian is the IERS Reference Meridian. It is derived but deviates slightly from the Greenwich Meridian, which was selected as an international standard in 1884.
Millennium Dome The Millennium Dome, also referred to simply as The Dome, is the original name of a large dome-shaped building, originally used to house the Millennium Experience, a major exhibition celebrating the beginning of the third millennium of the Anno Domini calendar era. Located on the Greenwich Peninsula in South East London, England, the exhibition was open to the public from 1 January to 31 December 2000. The project and exhibition was the subject of considerable political controversy as it failed to attract the number of visitors anticipated, with recurring financial problems. All of the original exhibition and associated complex has since been demolished. The dome still exists, however, and it is now a key exterior feature of The O2. The Prime Meridian passes the western edge of the Dome and the nearest London Underground station is North Greenwich on the Jubilee line.
