M6H-987 was a planet in the Pegasus galaxy. Janus' research outpost was located here, which was under the control of the Vanir before its destruction in 2008 during the Battle of M6H-987. The planet does not have a Stargate, and because Lt. Colonel John Sheppard and his team could not gate to the world, they traveled there using Katana Labrea's ship. Here two of the Vanir spaceships were destroyed, the Attero device was shut down and the outpost destroyed by Katana's ship. (SGA: "First Contact", "The Lost Tribe")
- Pegasus Chronicles, a fan made total conversion mod for Empire at war, gives the name of this planet as Aesculetum.
