"NGC7331 is an unbarred spiral galaxy approximately 40 million light years distant located in the constellation Pegasus. It is the brightest member of the NGC7331 group of galaxies and is approximately the same size as our Milky Way galaxy. The other members are lenticular or unbarred spirals, NGC7335 and 7336, the barred spiral galaxy NGC 7337 and the elliptical galaxy NGC 7340. These galaxies are at distances of approximately 332, 365, 348 and 294 million light years, respectively.  NGC 7331 is therefore unlikely to be interacting gravitationally with these galaxies. It is thought that NGC7331 has been tidally disrupted by a past encounter with Stephan's Quintet of galaxies which are relatively nearby".- Kurt Thrust current Director of the Jodrell Plank Observatory"
