NGC 3905 is a barred spiral galaxy in the constellation of Crater. Its velocity with respect to the cosmic microwave background is 6,130±26 km/s, which corresponds to a Hubble distance of 294.9 ± 20.7 Mly (90.41 ± 6.34 Mpc). However, six non-redshift measurements give a closer mean distance of 238.64 ± 20.80 Mly (73.167 ± 6.376 Mpc). It was discovered by English astronomer Andrew Ainslie Common in 1880.

NGC 3905 is Seyfert II galaxy, i.e. it has 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.

LDC 824 group

NGC 3905 is a member of the LDC 824 group of galaxies. This group contains 18 galaxies, including NGC 3702 [fr], NGC 3721 [fr], NGC 3722 [fr], NGC 3723 [fr], NGC 3763 [fr], NGC 3771 [fr], NGC 3791 [fr], NGC 3854 [fr], NGC 3858 [fr], IC 2910 [de], and seven others.
