NGC 4571 was one of the discoveries of
William Herschel who listed it as
H III.602. It was proposed as possible candidate for
M91 by John Herschel in his General Catalogue
(GC), and consequently in Dreyer’s NGC; we now know that M91 is very probably
NGC 4548 (H II.120). Nevertheless, these two galaxies forms a beautiful pair.
This galaxy is a member of the Virgo Cluster
of Galaxies. It has apparently a high peculiar motion toward us, as it
is receding from us with only 282 km/sec, compared to the cluster’s 1100 km/sec.
NGC 4571 came into discussion in summer 1994 when a group of astronomers at the
Canada France Hawaii Telescope (CFHT) used observations of 3 Cepheids in this
galaxy for a determination of the Hubble constant.
