NGC 1806 is a
interstellar extinction.[3]
NGC 1806 is about 1.6 billion years old. Its estimated mass is 7.6×104 M☉, and its total luminosity is 1.42×105 L☉, leading to a mass-to-luminosity ratio of 0.54 M☉/L☉.[3] All else equal, older star clusters have higher mass-to-luminosity ratios; that is, they have lower luminosities for the same mass.[3]
