NGC 5854 is a lenticular galaxy in the constellation of Virgo. Its velocity with respect to the cosmic microwave background is 1,851±14 km/s, which corresponds to a Hubble distance of 89.0 ± 6.3 Mly (27.30 ± 1.92 Mpc).[1] However, seven non-redshift measurements give a much closer mean distance of 60.95 ± 6.94 Mly (18.686 ± 2.128 Mpc).[2] It was discovered by German-British astronomer William Herschel on 24 February 1786.[3][4]
NGC 5846 group
[edit]According to A. M. Garcia, NGC 5854 is part of the NGC 5846 group (also known as LGG 393). This galaxy group has nine members, including NGC 5813 [fr], NGC 5831 [fr], NGC 5846, NGC 5864 [fr], NGC 5869 [fr], UGC 9746 [d], UGC 9760 [d], and UGC 9751 [d].[5] This group is part of the Virgo III Cloud.
Supernova
[edit]One supernova has been observed in NGC 5854:
- SN 1980P (type unknown, mag. 15) was discovered by S. Faber on 20 March 1980.[6][7] Although never officially classified, the discovery report claimed the supernova appeared to be of Type I, about 20 days after maximum.[6]
