Gemini

Abbreviation: Gem
Genitive: Germinorum
Right Ascension: 7.19 hours
Declination: 22.69 degrees

Gemini, the Twins, is visible from the Northern Hemisphere in November through April and in the Southern Hemisphere from December through March.

Gemini, the Twins were the sons of Leda who was seduced by Zeus who appeared as a swan, the result of the union was two eggs, one of which contained Helen of Troy and Pollux (the immortal twin) and the other egg were the offspring of Tyndareus, the mortal Castor and his sister Clytemnestra.

Castor a horseman and Pollux a boxer were inseparable and accompanied the Argonauts on their adventures. They calmed the seas when rough weather threatened. They can still be seen (or so sailors say) today when twin balls of lightening, or St. Elmos fire appear in the rigging of ships that sailors know foul weather is near.
