Encyclopedic overview

NGC 2848 is an intermediate spiral galaxy in the constellation of Hydra. Its velocity with respect to the cosmic microwave background is 2,361 ± 23 km/s, which corresponds to a Hubble distance of 34.82 ± 2.46 Mpc (~114 million light-years). It was discovered by German-British astronomer William Herschel on 31 December 1785.

To date, 13 non-redshift measurements give a distance of 18.892 ± 6.377 Mpc (~61.6 million light-years), which is outside the Hubble distance values. Since this galaxy is relatively close to the Local Group, it is likely that this value is closer to the true distance of NGC 2848. It is with the average value of independent measurements, when they exist, that the NASA/IPAC database calculates the diameter of a galaxy.
