NGC 874 is a spiral galaxy located in the Cetus constellation. It is estimated to be 572 million light-years away from the Milky Way galaxy and has a diameter of approximately 80,000 light-years. NGC 874 was discovered in 1886 by Frank Muller. [3] [6]
NGC 4639 is a barred spiral galaxy located in the equatorial constellation of Virgo. It was discovered by German-born astronomer William Herschel on April 12, 1784. John L. E. Dreyer described it as "pretty bright, small, extended, mottled but not resolved, 12th magnitude star 1 arcmin to southeast". This is a relatively nearby galaxy, lying approximately 72 million light-years away from the Milky Way. It is a companion to NGC 4654, and the two appear to have interacted roughly 500 million years ago. NGC 4639 is a member of the Virgo Cluster.
