NGC 5377

NGC 5377 is an intermediate barred spiral galaxy located in the constellation Canes Venatici. Its speed relative to the cosmic microwave background is 1,951 ± 11 km/s, which corresponds to a Hubble distance of 28.8 ± 2.0 Mpc. NGC 5377 was discovered by German-British astronomer William Herschel in 1787.
NGC 5377 was used by Gérard de Vaucouleurs as a morphological type galaxy SAb in his galaxy atlas.
The luminosity class of NGC 5377 is I and it has a broad HI line. NGC 5377 also has an active galactic nucleus which has been identified as a type 2 LINER.
To date, 17 non-redshift measurements yield a distance of 25.918 ± 5.770 Mpc, which is within the Hubble distance range. Note, however, that it is with the average value of independent measurements, when they exist, that the NASA/IPAC database calculates the diameter of a galaxy and that consequently the diameter of NGC 5377 could be approximately 37.7 kpc if Hubble distance is used to calculate it.

Nucleic disk

With observations from the Hubble Space Telescope, a star-forming disk was observed around the core of NGC 5377. The size of its semi-major axis is estimated at 790 pc.

Supermassive black hole

According to a study based on near-infrared K-band luminosity measurements of the nuclei of NGC 5377, a supermassive black hole with an apparent mass of approximately 10^7.8 exists within the core of the galaxy.

Supernova

Supernova SN 1992H was discovered on February 11, 1992, by William R. Wren of the McDonald Observatory at the University of Texas at Austin.

NGC 5448 group

NGC 5377 is a member of the NGC 5448 Group according to A.M. Garcia. The group has nine galaxies, including NGC 5425, NGC 5448, NGC 5481, NGC 5500, NGC 5520, UGC 9056 and UGC 9083.
