α Mus - The brightest star of the constellation, which reaches a magnitude of 2.94. At a distance of 29.6", it has a very faint companion with a magnitude of 12.8. It is located 306 light-years away from us.

β Mus - The elegant double star is composed of components of 4th magnitude orbiting around a common center of gravity once every 383 years. The current separation of the components is 1.6 arcseconds, which is a good test for a 100 mm telescope. The system is located 520 light-years away from us.

θ Mus - A binary star, whose components with magnitudes of 5.6 and 7.6 can be separated with a small telescope. The brighter star is a luminous blue supergiant, while its companion is an example of a Wolf-Rayet star - a hot star that has lost its outer layers.

N 1991 - In 1991, a nova erupted on the western edge of the constellation, designated as N 1991, which briefly became one of the brightest sources of X-ray radiation in the sky. It is believed to be a close binary star, with one component orbiting around a black hole, which can trigger processes leading to intense X-ray emission.
