NGC 3191 (also known as NGC 3192) is a
light years
from Earth, which, given its apparent dimensions, means that NGC 3191 is about 115,000 light years across.
The galaxy has been distorted and interacts with a companion about 0.5 arcminutes to the west, a galaxy identified as KUG 1015+467. An extremely blue tidal bridge lies between them.[2] It was discovered by Gaia on 23 May 2017.
Supernovae
Three supernovae have been observed in NGC 3191:
- SN 1988B (type Ia, mag. 15.5) was discovered by Paul Wild on 18 January 1988, 10" north of the galaxy's center.[3][4]
- PTF10bgl (type II-P, mag. unknown) was discovered by the Palomar Transient Factory on 6 February 2010.[5]
- SN 2017egm (type SLSN-I, mag. 16.72) was identified as a Type I superluminous supernova.[6] It is the closest supernova of this type observed and also the first to be found in a massive spiral galaxy.[7]
