- Source: Andromeda XXII
Andromeda XXII (Pisces VI, Triangulum I) is a low surface brightness dwarf spheroidal galaxy about 940–1,033 kiloparsecs (3.07×10^6–3.37×10^6 ly) away from the Sun in the constellation Pisces, of the Local Group.
Andromeda XXII is located much closer in projection to M33 than M31 [42 kiloparsecs (140×10^3 ly) vs. 224 kiloparsecs (730×10^3 ly)]. This fact suggests that it might be the first Triangulum (M33) satellite ever discovered. However, it is currently catalogued as a satellite of Andromeda (M31).
The discovery arose from the first year data of a photometric survey of the M31/M33 subgrouping of the Local Group by the Pan-Andromeda Archaeological Survey (PAndAS). This survey was conducted with the Megaprime/MegaCam wide-field camera mounted on the Canada-France-Hawaii Telescope.
