Comment

North is to the top.

NGC 2859 is a lenticular galaxy, located in the constellation Leo Minor, at a distance of about 85 million light-years. Lenticular galaxies have characteristics of both spiral and elliptical galaxies. NGC 2859 also has a strong bar, giving the galaxy the technical description of SBO. Also visible, in the above image, is a seemingly detached ring.
