Ophiucus system

The Ophiucus system was a star system.

Ophiucus III was a planet located in the system. 

In 2256, the USS Discovery (NCC-1031) drove off a Klingon attack in the system by utilizing their spore drive. This was later cited by Federation Starfleet Captain Gabriel Lorca as one of the crew's successes in a meeting with Admiral Katrina Cornwell.
