Encyclopedic overview
NGC 1846 is a globular cluster containing hundreds of thousands of stars in the outer halo of the Large Magellanic Cloud. It was discovered on November 6, 1826, by James Dunlop and is included in the New General Catalogue. At an aperture of 50 arcseconds, its apparent V-band magnitude is 10.68, but at this wavelength, it has 0.07 magnitudes of interstellar extinction.
NGC 1846 is about 1.7 billion years old. Its estimated mass is 5.7×10 M☉, and its total luminosity is 1.68×10 L☉, leading to a mass-to-luminosity ratio of 0.34 M☉/L☉. All else equal, older star clusters have higher mass-to-luminosity ratios; that is, they have lower luminosities for the same mass.
