Gemini is dominated by Castor and Pollux, two bright stars that appear relatively very closely together forming an o shape, encouraging the mythological link between the constellation and twinship. The twin above and to the right (as seen from the Northern Hemisphere) is Castor, whose brightest star is α Gem; it is a second-magnitude star and ...
IC 443 (also known as the Jellyfish Nebula and Sharpless 248 ) is a galactic supernova remnant (SNR) in the constellation Gemini. On the plane of the sky, it is located near the star Eta Geminorum. Its distance is roughly 5,000 light years from Earth. IC 443 may be the remains of a supernova that occurred 30,000 - 35,000 years ago.
It is located in the northern hemisphere, about 73 light-years from the Earth, in the constellation of Gemini. [12] It is visually close to Pollux, the brightest star in the constellation. [7] HD 63433 is predicted to approach within 7.33 light-years of the Sun in 1.33 million years. [21] That will make it one of the nearest stars to the Sun.
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.
Gamma Geminorum (γ Geminorum, abbreviated Gamma Gem, γ Gem), formally named Alhena / æ l ˈ h iː n ə /, [13] is the third-brightest object in the constellation of Gemini.It has an apparent visual magnitude of 1.9, [2] making it easily visible to the naked eye even in urban regions.
NGC 2291 is an unbarred lenticular galaxy in the constellation Gemini. It was discovered by John Herschel on January 22, 1827. [2] The visual magnitude is 13, and the apparent size is 1.0 by 0.8 arc minutes. [2]
The meteors will appear to stream from the constellation Gemini, which will rise in the northeastern sky. According to NASA, it’s best to view the Geminids by sitting back or lying down with ...
NGC 2266 is an open cluster [5] of stars in the constellation of Gemini. It was discovered by German-British astronomer William Herschel on 7 December 1785. [6] This is a relatively dim cluster with an integrated visual magnitude of 9.5 and an angular size of 5.0′. The stellar members can be readily resolved with an amateur telescope. [3]
