NGC 2305 is an elliptical galaxy in the constellation of Volans. Its velocity with respect to the cosmic microwave background is 3605 ± 21 km/s, which corresponds to a Hubble distance of 53.17 ± 3.75 Mpc. It was discovered by British astronomer John Herschel on 30 November 1834.
The galaxy NGC 2305 forms a physical pair with NGC 2307, collectively named RR 143, with a distance of at least 51 kpc between the galaxies.

Supernovae

Two supernovae have been observed in NGC 2305:SN 2011fn was discovered by Stu Parker on 29 June 2011. There is some uncertainty about this supernova; it was classified as either Type Ia or Type Ic, and it is possible that the host galaxy of this supernova was not NGC 2305, but instead the nearby galaxy 2MASS J06483060-6415588.SN 2023txv was discovered by ATLAS on 3 October 2023.
