NGC 4419 is a barred spiral galaxy in the constellation of Coma Berenices. It was discovered by German-British astronomer William Herschel on 8 April 1784. NGC 4419 has an apparent visual magnitude of 11.2 and spans an angular size of 3.3′ × 1.2′. It is a member of the Virgo Cluster of galaxies, and is moving through the cluster center at an extreme velocity. The nearest neighbor galaxy is NGC 4421 at a separation of 25′.
NGC 4419 is a LINER galaxy, i.e. a galaxy whose nucleus has an emission spectrum characterized by broad lines of weakly ionized atoms. It is inclined at an angle of 71° to the line of sight from the Earth. Mapping of the carbon monoxide distribution in the galaxy shows a significant spacial asymmetry.
Distance
NGC 4419 has a velocity with respect to the cosmic microwave background of 64±23 km/s, which is too small to be used to estimate its distance. Instead, 22 non-redshift measurements are used to give a mean distance of 52.49 ± 2.51 Mly (16.095 ± 0.771 Mpc).
Supernovae
Two supernovae have been observed in NGC 4419:
- SN 1984A (Type Ia, mag. 16) was discovered by Givi N. Kimeridze on 4 January 1984, and independently by Leonida Rosino on 7 January 1984.
- SN 2012cc (Type II, mag. 18.2) was discovered by the Lick Observatory Supernova Search (LOSS) on 29 April 2012.
