The luminosity class of NGC 626 is III and it has a broad HI[4] line.
NGC 626 has a surface brightness equal to 14.13 mag/am2,[5] which classifies NGC 626 as a low surface brightness galaxy (LSB).[5] LSB galaxies are diffuse (D) galaxies with a surface brightness less than one magnitude lower than that of the ambient night sky.
