Mercer 3 is a heavily obscured globular cluster embedded in the disk of the Milky Way galaxy.[1] It was discovered in 2008 in the data obtained by 2MASS and GLIMPSE infrared surveys. The cluster is located in the Scutum constellation. It had avoided detection for such a long time due to the extremely strong foreground extinction in its direction reaching 24 magnitudes in the visible light. Mercer 3 is probably situated at the distance from 4 to 8 kpc from the Sun and has a half-light radius of 0.7–1.5 pc.[1]

Mercer 3 is an old globular cluster having the age of about 12 billion years. The mass of cluster is estimated at 2–3 hundred thousand solar masses.[1]
