NGC 7343 is a barred spiral galaxy located in theconstellation Pegasus. Its velocity relative to thecosmic microwave background is 7150 ± 24 km/s, which corresponds to aHubble distance of 105.5 ± 7.4 Mpc (~344 millionly). NGC 7343 was discovered by American astronomerTruman Safford in 1866. It was independentlyrediscovered by French astronomerÉdouard Stephan on September 27, 1873.
Theluminosity class of NGC 7343 is II-III and it has a broad HI line. In addition, it is also aLINER galaxy, a galaxy whose nucleus presents an emission spectrum characterized by broad lines of weakly ionized atoms. To date, eight non-redshift measurements yield a distance of 65.787 ± 44.256 Mpc (~215 million ly), which is outside the Hubble distance values.[2][3][1][4][5]
