- Castor is the second-brightest object in the zodiac constellation of Gemini. It has the Bayer designation α Geminorum, which is Latinised to Alpha Geminorum and abbreviated Alpha Gem or α Gem. With an apparent visual magnitude of 1.58, it is one of the brightest stars in the night sky. Castor appears singular to the naked eye, but it is actually a sextuple star system organized into three binary pairs. Although it is the ‘α’ (alpha) member of the constellation, it is fainter than ‘β’ (beta) Geminorum, Pollux.
Thousands of geniuses live and die undiscovered — either by themselves or by others. But for the Civil War, Lincoln and Grant and Sherman and Sheridan would not have been discovered, nor have risen into notice. … I have touched upon this matter in a small book which I wrote a generation ago and which I have not published as yet — Captain Stormfield’s Visit to Heaven. When Stormfield arrived in heaven he … was told that … a shoemaker … was the most prodigious military genius the planet had ever produced.
Mark Twain
