NGC 2357 est une galaxie spirale vue par la tranche et située dans la constellation des Gémeaux. Sa vitesse par rapport au fond diffus cosmologique est de 2 433 ± 11 km/s, ce qui correspond à une distance de Hubble de 35,9 ± 2,5 Mpc (∼117 millions d'al) [1]. NGC 2357 a été découverte par l'astronome français Édouard Stephan en 1885 [3].

NGC 2357 is a Spiral Galaxy in the Gemini constellation. NGC 2357 is situated close to the celestial equator and, as such, it is at least partly visible from both hemispheres in certain times of the year. Given its B magnitude of 14.6, NGC 2357 is visible with the help of a telescope having an aperture of 20 inches (500mm) or more.

2025年1月28日 · Ngc 2357 is a galaxy in Gemini ; magnitude: 14.5 ; size: 3.2' x 0.5' ; very faint edge on, averted vision only. Probably one of the faintest and hardest to see galaxies I have observed. I used a 8mm Ethos at 240x with my 14.5 StarStructure f/4.3

This object is a rarely imaged edge-on galaxy located 100 million light years away in the constellation of Gemini at a declination of +23 degrees. This magnitude 14 galaxy spans 4.5 arc-minutes in our apparent view, which corresponds to a diameter of 130,000 light years. Not much has been written about this galaxy.
