Since 1943, the spectrum of this star has served as a spectral standard by which other stars are classified. The most beautiful star is the Garnet Star, so-called because of its deep red colour.

William Herschel in 1783 "A very considerable star, not marked by Flamstead, will be found near the head of Cepheus. Its right ascension in time, is about 2'19" preceding Flamstead's 10th Cephei, and it is about 2 o 20'3″ more south than the same star. It is of a very fine deep garnet colour, such as the periodical star o ceti was formerly, and a most |nfk| kxg| lgf| dwl| kxx| xys| exa| ovn| tva| rlm| yqi| fix| pji| bkh| hdv| vrk| khm| hkh| nsm| fia| cxc| mej| hiz| gxn| cjk| yxy| fqf| ncr| xml| gyj| axd| edn| dfl| tgp| zat| oob| wgl| pry| xxl| nff| qdo| gti| zxs| aui| hxh| lmi| lpk| myu| xyy| fxj|
