Together, the G objects and high-velocity stars constitute the S cluster. In contrast with theoretical predictions, no binary system near Sgr A* has been identified. Here, we report the detection of a spectroscopic binary system in the S cluster with the masses of the components of 2.80 $\\pm$ 0.50 M$_{\\odot}$ and 0.73 $\\pm$ 0.14 M$_{\\odot}$, assuming an edge-on configuration.
