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]
