UGC 711 is a relatively nearby 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 V_circ = 92 km s⁻¹ according to measurements from Hyperleda.^[12]
