The Twins and an Orangey Moon
Ranked as the seventeenth and twenty-third brightest stars, the guide posts to the Twins of Gemini are now located high in the night sky. Their names respectively are Pollux and Castor and shine at magnitudes 1.14 and 1.57. Pollux is a giant orange star that seems to have a hot outer corona like out Sun. It does possess a fainter companion too close to be resolved by amateur telescope. Although it is brighter than Castor Bayer for some reason gave the designation of alpha (the brightest) to Castor. With a good telescope, three of Castor’s stars can be resolved; however these are really three double stars giving us a total of six suns that appear as one to the unaided eye.
