NGC 6018 is a 13.4 mag bright, lens-shaped galaxy of the Hubble-type S0-a in the constellation Snake near the celestial equator . It is an estimated 241 million light years from the Milky Way. Together with NGC 6021, the galaxy forms an optical double galaxy and was discovered on March 19, 1787 by Wilhelm Herschel with an 18.7-inch reflector telescope, who described it as “vF, S, lE”.
Most likely, NGC 6018 is identical to IC 1150 . It is the only object in this region to which the observation by Stéphane Javelle in July 1891 applies (with a positional error) .
