NGC 5378 is a barred spiral galaxy in the constellation of Canes Venatici. Its velocity with respect to the cosmic microwave background is 3,176±14 km/s, which corresponds to a Hubble distance of 152.8 ± 10.7 Mly (46.85 ± 3.29 Mpc).[1] It was discovered by British astronomer John Herschel on 11 March 1831.[2][3]

NGC 5378 is a LINER galaxy, i.e. a galaxy whose nucleus has an emission spectrum characterized by broad lines of weakly ionized atoms.[4][5]

NGC 5378 group

NGC 5378 is a member the NGC 5378 group (also known as LGG 364), which contains three galaxies, including NGC 5380 and UGC 8778.[6][7]
