Shining at a maginitue of 9.6, NGC 4565 appears as a 16'-long needle of light. The flattened disk displays bright and dark patches with much clumpiness and branching. As with NGC 891, photographs also show dark fingers of dust projecting above and below of the equatorial plane.
We now know that NGC 4565 is a member of the local Coma-Sculptor group. With an accepted distance of 32 million light-years, the true diameter of the galaxy is about 150'000 light-years.
