While there are some candidates, they lack clear and convincing confirmation and remain controversial. Beyond the innate value of discovering new types of objects in the Universe, satellites can help give key insights into planet formation mechanisms and the dynamical evolution histories of their systems. In this work, we show strong evidence for the existence of satellites orbiting the directly-imaged brown dwarf companion CD-35 2722 B.
