Earth
As of 2012 the most used prime meridian for the Earth is the IERS Reference Meridian (IRM). It passes about 5.3 arcseconds east of Airy's transit circle or about 102 metres (335 ft) at the latitude of the Royal Observatory, Greenwich, London. A current convention on the Earth uses the opposite of the IRM as the basis for the International Date Line.

Famous quotes containing the word earth:
“The earth is ready, the time is ripe, for the authoritative expression of the feminine as well as the masculine interpretation of that common social consensus which is slowly writing justice in the State and fraternity in the social order.”
—Anna Garlin Spencer (1851–1931)
“War was return of earth to ugly earth,
War was foundering of sublimities,
Extinction of each happy art and faith
By which the world had still kept head in air.”
—Robert Graves (1895–1985)
“Heaven has its business and earth has its business: those are two separate things. Heaven, that’s the angels’ pasture; they are happy; they don’t have to fret about food and drink. And you can be sure that they have black angels to do the heavy work like laundering the clouds or sweeping the rain and cleaning the sun after a storm, while the white angels sing like nightingales all day long or blow in those little trumpets like they show in the pictures we see in church.”
—Jacques Roumain (1907–1945)
