Pisces VII belongs to the family of the Andromeda Galaxy (M31).
Since 2013, a new satellite of M31 had not been discovered because its minor satellites are extremely weak, in fact Pisces VII is the faintest galaxy discovered so far outside the domain of the Milky Way.
I discovered it on 1 September 2020 in the DECam images and confirmed by the Telescopio Nazionale Galileo - TNG (image).
