Prime Meridian - Earth

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:

    Still they stood,
    A great wave from it going over them,
    As if the earth in one unlooked-for favor
    Had made them certain earth returned their love.
    Robert Frost (1874–1963)

    And what is so rare as a day in June?
    Then, if ever, come perfect days;
    Then Heaven tries earth if it be in tune,
    And over it softly her warm ear lays:
    Whether we look, or whether we listen,
    We hear life murmur, or see it glisten;
    James Russell Lowell (1819–1891)

    Surely, of all creatures we eat, we are most brutal to snails. Helix optera is dug out of the earth where he has been peacefully enjoying his summer sleep, cracked like an egg, and eaten raw, presumably alive. Or boiled in oil. Or roasted in the hot ashes of a wood fire.... If God is a snail, Bosch’s depictions of Hell are going to look like a vicarage tea-party.
    Angela Carter (1940–1992)
