V616 Monocerotis (A0620-00) is the third nearest black hole system to Earth, about 4,700 light-years away in the constellation Monoceros. In 2018-Jun-15, a radio signal was sent to this black hole in memory of the late Dr. Stephen Hawking, who died three months prior.
(NOTE: Black hole addons tend to be performance heavy and might not work in all devices)
