NGC 3613 is an elliptical galaxy in the constellation Ursa Major.[1] It was discovered by the Grman-British astronomer William Herschel on 8 April 1793.[5] The galaxy has an apparent visual magnitude of 10.8 with an angular size of 3.9′ × 1.1′.[1] It is located at a distance of 98 million light-years (30.1 Mpc). NGC 3613 is positioned at the center of a cluster of 12 galaxies that includes NGC 3610.[4]

The morphological classification of NGC 3613 is E6,[4] indicating an elliptical galaxy with a pronounced oval shape. It has an estimated globular cluster population of over 2,000 members.[4] One supernova event has been observed in NGC 3613: SN 2011eh. This Type Ia-pec supernova was discovered by Masaki Tsuboi on 20 July 2011 and reached magnitude 16.2.[6][7][8]
