NGC 3353

NGC 3353 is an intermediate spiral galaxy located in the constellation of Ursa Major.^[2][3] Its velocity with respect to the cosmic microwave background is 1108 ± 12 km/s, which corresponds to a Hubble distance of 53.3 ± 3.8 Mly (16.35 ± 1.16 Mpc).^[1] In addition, four non-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, by William Herschel,^[5] a German born British astronomer.^[6]
