From The Stargate Omnipedia


Nickname for "Ernest's Planet," PB2-908. After failed experiments to uncover the mysteries of the Stargate, Ernest Littlefield was trapped on this world. During his more than 50 years there, Dr. Littlefield determined that the planet was once a meeting place for the exchange of knowledge and culture for four great races -- who SG-1 later identified as the Asgard, the Nox, the Furlings, and the Ancients.

SG-1 rescued Dr. Littlefield from Heliopolis, only to discover that the planet's Stargate has fallen into the ocean. The planet is no longer reachable by Stargate.
