UGC 711
Galaxy in the constellation Cetus
From Wikipedia, the free encyclopedia
UGC 711 is a spiral galaxy located in the constellation of Cetus. Estimated to be located 77 million light-years from Earth,[1] the galaxy's luminosity class is IV and it has a HI line width region.[clarification needed][2] It belongs to the equatorial region of Eridanus Void with an arcsec approximation of ≈ 250.[clarification needed][3]

Morphology
UGC 711 is considered a low-surface brightness galaxy (LSB)[4] with a diffuse stellar disk.[5][6]
With a surface brightness measurement found ~1 magnitude less illuminated compared to μ B,0 = 21.65 mag arcsec−2 according to K.C. Freeman,[7] UGC 711 is one of best studied superthin galaxies defined by its atypical classification when seen edge-on.[8][9][10] It has a flat structure with only a diameter estimating to be a = 40 arcsecs but has a major-to-minor axis ratio wider than 7 arcsecs.[11]
The rotational velocity of UGC 711 is said to be only Vcirc = 92 km s−1 according to measurements from Hyperleda.[12]
