NGC 2935 is a large intermediate spiral galaxy located in the constellation Hydra. Its speed relative to the cosmic microwave background is 2,601 ± 23 km/s, which corresponds to a Hubble distance of 38.4 ± 2.7 Mpc (~125 million ly). It was discovered by German-British astronomer William Herschel on 20 March 1786.
NGC 2935 was used by Gérard de Vaucouleurs as a galaxy of morphological type (R2')SAB(s)b in his galaxy atlas. The luminosity class of NGC 2935 is II and it has a broad HI line. In addition, it is a star-forming burst galaxy.
To date, 29 studies and measurements based on redshift give a distance of 27.890 ± 3.962 Mpc (~91 million ly), which is outside the Hubble distance values. Note that it is with the average value of independent measurements, when they exist, that the NASA/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.




Nuclei disk


Observations from the Hubble 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.




Supernovae


Four supernovae have been discovered in NGC 2935. SN 1975F (type unknown, mag. 15) was discovered on 11 June 1975, by Mr. J. R. Dunlap of the Corralitos Observatory at Northwestern University. SN 1996Z (type Ia, mag. 16) was discovered on 16 May 1996 by Wayne Johnson. SN 2021mwj (type II, mag. 17.7) was discovered on 21 May 2021 by ATLAS. SN 2021aczp (type II, mag. 18.9) was discovered on 1 November 2021 by ATLAS.




NGC 2935 Group


NGC 2935 is part of a small group of three galaxies named after it. The other two galaxies in the NGC 2935 group are NGC 2983 and NGC 2986.
