Sunset

Sunset or sundown is the daily disappearance of the Sun below the horizon in the west as a result of Earth's rotation.

The time of sunset is defined in astronomy as the moment when the trailing edge of the Sun's disk disappears below the horizon in the west. The ray path of light from the setting Sun is highly distorted near the horizon because of atmospheric refraction, making the sunset appear to occur when the Sun’s disk is already about one diameter below the horizon. Sunset is distinct from dusk, which is the moment at which darkness falls, which occurs when the Sun is approximately eighteen degrees below the horizon. The period between sunset and dusk is called twilight.

Locations north of the Arctic Circle and south of the Antarctic Circle experience no sunset or sunrise at least one day of the year, when the polar day or the polar night persist continuously for 24 hours.

Sunset creates unique atmospheric conditions such as the often intense orange and red colors of the Sun and the surrounding sky.

Famous quotes containing the word sunset:

    When the
    Marne flowed by the plants nodded
    And above the glistering Gila
    A sunset as beautiful as the Athabasca
    Stammered. The Zambezi chimed. The Oxus
    Flowed somewhere.
    John Ashbery (b. 1927)

    The word “conservative” is used by the BBC as a portmanteau word of abuse for anyone whose views differ from the insufferable, smug, sanctimonious, naive, guilt-ridden, wet, pink orthodoxy of that sunset home of the third-rate minds of that third-rate decade, the nineteen-sixties.
    Norman Tebbit (b. 1931)

    The sumptuous age of stars and images is reduced to a few artificial tornado effects, pathetic fake buildings, and childish tricks which the crowd pretends to be taken in by to avoid feeling too disappointed. Ghost towns, ghost people. The whole place has the same air of obsolescence about it as Sunset or Hollywood Boulevard.
    Jean Baudrillard (b. 1929)
