NGC 4041 is an active spiral galaxy of the Hubble type Sbc ( Vaucouleurs type SA (rs) bc) with extensive star formation areas in the constellation Great Bear in the northern sky . The morphological classification of SA (rs) bc indicates that this is a spiral galaxy that lacks a bar ; the 'rs' means it has a weakly shaped ring structure , and the 'bc' indicates that the spiral arms are moderately to loosely wound. It is estimated to be 60 million light years from the Milky Way and about 45,000 light years across.
Together with NGC 4036 , IC 758 , UGC 7009 and UGC 7019 , it forms the NGC 4036 galaxy group ( LGG 266 )
On July 29, 1994, the Type IIp supernova SN 1994W was observed in this galaxy.
The object was discovered on March 19, 1790 by the astronomer Wilhelm Herschel with the help of an 18.7 inch reflector telescope.
