Arcturus    音标拼音: [,ɑrkt'ʊrəs] [,ɑrkt'ɚəs]
n. 大角星

大角星

Arcturus
n 1: the 4th brightest star and the brightest star in the
constellation Bootes; 36 light-years from Earth

Arcturus \Arc*tu"rus\, n. [L. Arcturus, Gr. ? bearward, equiv.
to ?; ? bear ? ward, guard. See {Arctic}.] (Anat.)
A fixed star of the first magnitude in the constellation
Bo["o]tes.
[1913 Webster]

Note: Arcturus has sometimes been incorrectly used as the
name of the constellation, or even of Ursa Major.
[1913 Webster]

Canst thou guide Arcturus with his sons [Rev.
Ver.: "the Bear with her train"]. --Job xxxviii.
32.
[1913 Webster]

Arcturus
bear-keeper, the name given by the ancients to the brightest
star in the constellation Bootes. In the Authorized Version (Job
9:9; 38:32) it is the rendering of the Hebrew word _'ash_, which
probably designates the constellation the Great Bear. This word
('ash) is supposed to be derived from an Arabic word meaning
night-watcher, because the Great Bear always revolves about the
pole, and to our nothern hemisphere never sets.
