NGC 3888 is an intermediate spiral galaxy in the constellation of Ursa Major. Its velocity with respect to the cosmic microwave background is 2,560±12 km/s, which corresponds to a Hubble distance of 123.2 ± 8.6 Mly (37.76 ± 2.65 Mpc).[1] Additionally, six non-redshift measurements give a farther mean distance of 129.97 ± 2.51 Mly (39.850 ± 0.770 Mpc).[2] It was discovered by German-British astronomer William Herschel on 14 April 1789.[3][4]

NGC 3888 is a starburst galaxy.[1] It also has a nucleus which shines in the ultraviolet range, and is thus listed in Markarian's catalogue as Mrk 188.[5]

NGC 3780 group

[edit]

NGC 3888 is a member of the NGC 3780 group (also known as LGG 247). This group contains 4 galaxies, including NGC 3780, UGC 6596 [d], and UGC 6774 [d].[6][7]

Supernova

[edit]

One supernova has been observed in NGC 3888:

  • SN 2015Q (Type Ib, mag. 16) was discovered by American amateur astronomer Patrick Higgins on 17 June 2015.[8][9]
