    6936|| || ||Rigel (Beta Orionis)|| ||Blue supergiant and double star || ||0.1 and 6.7 mag|| ||9.4" apart || ||>=6"|| ||Rigel is one of the brightest stars in the sky and most luminous stars in the galaxy at an impressive zero magnitude with a distance of somewhere between 700 and 900 light years means it has a luminosity in excess of 40000 times that of the Sun. Its visual binary companion is much fainter and difficult to see due to the primary's brightness. With a physical separation of roughly 2000 AU, no orbital motion has been detected, but they both exhibit similar proper motions trajectories.||||[http://en.wikipedia.org/wiki/Rigel 1] [http://www.astro.uiuc.edu/~kaler/sow/rigel.html 2]||
    7037|| || ||Betelgeuse (Alpha Orionis)|| ||Red supergiant|| ||0.2-1.5|| || || ||naked eye|| ||600 ly distant. Radius is 100 times that of Sun, and luminosity is 100,000 times that of the Sun. One of the largest stars known, and one of the first stars to be resolved by optical interferometers. Observations have revealed starspots and variable size. A core collapse supernova is imminent.|| ||[http://en.wikipedia.org/wiki/Betelgeuse 1] [http://www.astro.uiuc.edu/~kaler/sow/betelgeuse.html 2]||
