It's a visual grup fromed by five galaxys, it was the first one to be discovered, the scientits Édouard Stephan found it in a observatory in 1877.
It's the most studied compact galaxy grup, it's formed by five members, NGC 7317, 7318A/B, 7319, and 7320.
I've analised HCG 92 spectrum, and mesured the higgest pic to know wich is the principal element that formes this object.
→Vanadium (V)
As I mention in NGC 7331 section Vanadium is a really commun element in galaxies.
