naked eye star Milky Way greater than 1000 Kelvin from the point of view of Earth's orbit for many centuries asterism naked eye object brighter than 5 A star visible without visual aids

subgiant greater than 1000 Kelvin from the point of view of Earth's orbit star A star whose position on the H-R diagram is intermediate between that of main-sequence stars and normal giants of the same spectral type. IV

visual binary greater than 1000 Kelvin from the point of view of Earth's orbit half the stars in the solar neighborhood are members of star systems binary star A binary star which can be resolved into two components with current telescopes. 2
