NGC 5230 is a spiral galaxy in the constellation of Virgo. Its velocity with respect to the cosmic microwave background is 7,150±20 km/s, which corresponds to a Hubble distance of 344.0 ± 24.1 Mly (105.46 ± 7.39 Mpc).[1] However, six non-redshift measurements give a much closer mean distance of 80.34 ± 8.75 Mly (24.633 ± 2.683 Mpc).[2] It was discovered by German-British astronomer William Herschel on 12 April 1784.[3]
NGC 5230 group
[edit ]According to Abraham Mahtessian, NGC 5230 is a member of a galaxy group named after it. The other galaxies in the group are NGC 5221 and NGC 5222 [fr].[4]
Supernovae
[edit ]Two supernovae have been observed in NGC 5230:
- SN 1970P (type unknown, mag. 17.2) was discovered by Mnatskanian on 4 June 1970.[5]
- SN 2026fjy (Type II-P, mag. 19.737) was discovered by ATLAS on 10 March 2026.[6]
