NGC 4634 is an edge-on barred spiral galaxy [4] located about 70 million light-years away in the constellation of Coma Berenices. [5] NGC 4634 was discovered by astronomer William Herschel on January 14, 1787. [6] It is interacting with the spiral galaxy NGC 4633. [5] Both galaxies are members of the Virgo Cluster. [7] [8]
