NGC 735 is a spiral galaxy in the constellation of Triangulum. Its velocity with respect to the cosmic microwave background is 4374 ± 18 km/s, which corresponds to a Hubble distance of 210.4 ± 14.7 Mly (64.52 ± 4.52 Mpc).[1] In addition, eight non redshift measurements give a distance of 227.21 ± 7.99 Mly (69.662 ± 2.449 Mpc).[2] The galaxy was discovered by German-British astronomer William Herschel on 13 September 1784).[3]
The SIMBAD database lists NGC 735 as a radio galaxy.[4]
Supernovae
[edit]Three supernovae have been observed in NGC 664. American astronomer John Huchra discovered SN 1972L (type unknown, mag. 15)[5] on 3 September 1972. The other 2 supernovae are: SN 2000dj (type II, mag. 17.4)[6] and SN 2006ei (type Ic, mag. 18.5).[7]
NGC 669 Group
[edit]NGC 735 is a member of the NGC 669 group (also known as LGG 37). This group contains 34 galaxies, of which 15 are in NGC, 11 are in UGC, and 3 are in IC.[8]
