Spiral galaxy in the constellation Leo
NGC 3840 is a
spiral galaxy
[2] located about 320 million
light-years away
[3] in the constellation
Leo.
[4] The galaxy was discovered by astronomer
Heinrich d'Arrest on May 8, 1864.
[5] NGC 3840 is a member of the
Leo Cluster.

[7]
[8] The galaxy is rich in
neutral atomic hydrogen (H I) and is not
interacting with its environment.
[9]
NGC 3840 is likely to be a low-luminosity
AGN (LLAGN).
