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).^[1] It was discovered by German-British astronomer William Herschel on 6 January 1785.^[2] This galaxy was also observed by British astronomer John Herschel on 12 March 1826, and later listed as NGC 2727.^[2]

The SIMBAD database lists NGC 2708 as a Seyfert II galaxy,^[3] 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.

One supernova has been observed in NGC 2708: SN 2023bee (type Ia, mag. 17.2621) was discovered by the Distance Less Than 40 Mpc Survey (DLT40) on 1 February 2023.^[4]

According to A.M. Garcia, NGC 2708 is the namesake of the four member NGC 2708 group (also known as LGG 164). The other three galaxies are: NGC 2695, NGC 2699, and NGC 2706.^[5]
