Constellation Gemini
The Gemini constellation is one of the most well-known and easily recognizable constellations in the night sky. It is named after the Latin word for “twins”, representing the mythological twin brothers Castor and Pollux.
Located in the northern celestial hemisphere, Gemini is part of the zodiac and can be seen between the months of December and February. It is positioned between Taurus to the east and Cancer to the west.
The constellation is characterized by its two brightest stars, Castor and Pollux, which serve as “heads” of the celestial twins. Castor, also known as Alpha Geminorum, is a multiple star system composed of six individual stars. Pollux, or Beta Geminorum, is the brightest star in the constellation and is a giant yellow-orange star located approximately 34 light-years away from Earth.
Gemini is also home to several other interesting celestial objects:
- Messier 35 (M35): Open star cluster located near the foot of Castor. It contains over 300 stars and is easily visible with binoculars or a small telescope.
- Nova Geminorum 1912: A nova (a star that suddenly increases in brightness) that appeared in Gemini in 1912. Although it faded over time, it is still possible to observe the affected star.
- NGC 2371/NGC 2372: Twin planetary nebulae located within the constellation. These glowing shells of gas were expelled by dying stars.
Astrology enthusiasts believe that people born under the Gemini sign (between May 21 and June 21) often possess characteristics associated with the twins, such as curiosity, adaptability, and versatility.
