NGC 3632 (also known as Caldwell 40) and NGC 3626[6] is an unbarred lenticular galaxy[5] and Caldwell object in the constellation Leo. It was discovered by William Herschel, on 14 March 1784. It shines at magnitude +10.6[6]/+10.9. Its celestial coordinates are RA 11h 20.1m , dec +18° 21′. It is located near the naked-eye-class A4 star Zosma, as well as galaxies NGC 3608, NGC 3607, NGC 3659, NGC 3686, NGC 3684, NGC 3691, NGC 3681, and NGC 3655. Its dimensions are 2′.7 × 1′.9.[6] The galaxy belongs to the NGC 3607 group some 70 million light-years distant, itself one of the many Leo II groups.[7]
