NGC 473

NGC 473 is a lenticular galaxy in the constellation of Pisces.^[2] Its velocity with respect to the cosmic microwave background is 1819 ± 22 km/s, which corresponds to a Hubble distance of 87.5 ± 6.2 Mly (26.82 ± 1.91 Mpc).^[1] In addition, one non redshift measurement gives a distance of 97 Mly (29.8 Mpc).^[3] It was discovered on December 20, 1786 by William Herschel.^[2]
