NGC 7300 is an intermediate spiral galaxy in the constellation of Aquarius. Its velocity with respect to the cosmic microwave background is 4,566±24 km/s, which corresponds to a Hubble distance of 219.7 ± 15.4 Mly (67.35 ± 4.73 Mpc).[1] However, 15 non-redshift measurements give a closer mean distance of 181.89 ± 10.31 Mly (55.767 ± 3.162 Mpc).[2] It was discovered by British astronomer John Herschel on 26 July 1830.[3]
NGC 7300 group
NGC 7300 is the namesake of a small group of galaxies. The other galaxies in the NGC 7300 group (also known as LGG 458) are NGC 7251, NGC 7298, MCG -03-57-001, and MCG -03-57-008.[4][5]
Supernovae
Two supernovae have been observed in NGC 7300:
- SN 1996ca (Type Ia, mag. 16.5) was discovered by Masakatsu Aoki on 15 December 1996.[6][7]
- SN 2015au (Type IIb, mag. 17.7) was discovered by Greg Bock as part of the Backyard Observatory Supernova Search (BOSS) on 10 November 2015.[8][9]
