NGC 2708 is a spiral galaxy in the constellation of Hydra. Its velocity with respect to the cosmic microwave background is 2315 ± 22 km/s, which corresponds to a Hubble distance of 34.15 ± 2.41 Mpc (~111 million light-years). It was discovered by German-British astronomer William Herschel on 6 January 1785. This galaxy was also observed by British astronomer John Herschel on 12 March 1826, and later listed as NGC 2727.

The SIMBAD database lists NGC 2708 as a Seyfert II galaxy, i.e. a galaxy with a quasar-like nucleus with very high surface brightnesses whose spectra reveal strong, high-ionisation emission lines, but unlike quasars, the host galaxy is clearly detectable.
