NGC 4689 is a spiral galaxy located about 54 million light-years away[2] in the constellation of Coma Berenices.[3] NGC 4689 is also classified as a LINER galaxy.[2] NGC 4689 is inclined at an angle of about 36° which means that the galaxy is seen almost face-on to the Earth's line of sight.[4] NGC 4689 was discovered by astronomer William Herschel on April 12, 1784.[5] The galaxy is a member of the Virgo Cluster.[6][7]
