NGC 3353 is anintermediate spiral galaxy located in theconstellation ofUrsa Major.[2][3] Its velocity with respect to thecosmic microwave background is 1108 ± 12 km/s, which corresponds to aHubble distance of 53.3 ± 3.8 Mly (16.35 ± 1.16 Mpc).[1] In addition, fournon-redshift measurements give a distance of 62.46 ± 2.66 Mly (19.150 ± 0.817 Mpc).[4] NGC 3353 was discovered on March 18, 1790, byWilliam Herschel,[5] aGerman bornBritishastronomer.[6]
NGC 3353 is a galaxy whose nucleus shines in theultraviolet range. It is listed in theMarkarian catalogue as Mrk 35.
NGC 3353 is part of theNGC 3264group (also known asLGG 201), which includes at least five other members:NGC 3206,NGC 3220, NGC 3264, UGC 5848, and UGCA 211.[7]
