NGC 5394


NGC 5394 is a barred [spiral galaxy] located in the constellation Canes Venatici. Its speed relative to the cosmic microwave background is 3,639 ± 14 km/s, which corresponds to a Hubble distance of 53.7 ± 3.8 Mpc. NGC 5394 was discovered by German-British astronomer William Herschel in 1787.
The luminosity class of NGC 5394 is II and it has a broad HI line. It also contains regions of ionized hydrogen. It is also a Luminous Infrared Galaxy.
To date, one non-redshift-based measurement gives a distance of approximately 32,900 Mpc. This value is far outside the Hubble distance values. Note that it is with the average value of independent measurements, when they exist, that the NASA/IPAC database calculates the diameter of a galaxy.
One supernova has been observed in NGC 5394: SN 2020aaxs was discovered by the Automatic Learning for the Rapid Classification of Events on 25 November 2020.

Arp 84

NGC 5394 and NGC 5395 are a pair of gravitationally interacting galaxies that appear in Halton Arp's Atlas of Peculiar Galaxies under the designation Arp 84. Arp noted that NGC 5495 is a spiral with a high surface luminosity companion at the end of one of its arms.

NGC 5395 group

According to A.M. Garcia, NGC 5394 is part of a group of galaxies that has at least five members, the NGC 5395 group. The other galaxies are NGC 5341, NGC 5351, NGC 5395 and UGC 8806.
