NGC 2935

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.
