Arcturus

ark-tu'rus, as supposed by many astronomers, the nearest of the stars. It is situated in the constellation Bootes in the northern heavens. It shines with a red light. It is supposed to be a body like our own sun. It is evidently moving southward slowly through the heavens. It has moved a degree since the days of Ptolemy. It is thought by Professor C. A. Young that "Arcturus gives the earth as much heat as would be received from a standard candle 5.8 miles away." One writer hazards the statement that Arcturus is 1,500,000 times as far away as the sun, that it has a diameter of 71,000,000 miles, and that its bulk is 551,000 times that of the sun. See Star
