NGC 2935 is a largeintermediate spiral galaxy located in theconstellation Hydra. Its speed relative to thecosmic microwave background is 2,601 ± 23 km/s, which corresponds to aHubble distance of 38.4 ± 2.7 Mpc (~125 million ly). It was discovered by German-BritishastronomerWilliam Herschel on 20 March 1786.[1][2]
NGC 2935 was used byGérard de Vaucouleurs as a galaxy of morphological type (R2')SAB(s)b in his galaxy atlas. Theluminosity class of NGC 2935 is II and it has a broad HI line. In addition, it is astar-forming burst galaxy.[3]
To date, 29 studies and measurements based onredshift give a distance of 27.890 ± 3.962 Mpc (~91 million ly),[4] which is outside the Hubble distance values. Note that it is with the average value of independent measurements, when they exist, that theNASA/IPAC database calculates the diameter of a galaxy and that consequently the diameter of NGC 2935 could be approximately 78, 1 kpc (~255,000 ly) if we used the Hubble distance to calculate it.[5]
Observations from theHubble Space Telescope have concluded that a star-forming disk is present around the core of NGC 2935. The size of its semi-major axis is estimated at 530 pc (~1730 light years) at the estimated distance of this galaxy.[6]
Foursupernovae have been discovered in NGC 2935:
NGC 2935 is part of a smallgroup of three galaxies named after it. The other two galaxies in the NGC 2935 group areNGC 2983 andNGC 2986.[13]
