The brightest star of the constellation has an apparent magnitude of 3.95. It belongs to a beautiful triple star system discovered by W. Herschel in 1781, whose all blue-white components can be resolved even with small telescopes as a small triangle. Two components with magnitudes of 4.7 and 5.2 are located at a separation of 7.3 arcseconds. A companion with a magnitude of 6.1 is situated at a distance of 2.8 arcseconds from the first component. The system is approximately 700 light-years away. With a larger telescope, we can also discover a star with a magnitude of 12 at a separation of 25.9 arcseconds. This entire system is designated as 11 Mon.
