Adara II

Adara II is an uninhabitable planet in the Milky Way galaxy. A member of the Protected Planets Treaty, it was the site of the Asgard Heimdall's lab, where he conducted research on an Asgard found six months earlier. Osiris eventually intruded on the planet. Thor arrived in a Bilskirnir-class ship, believing that the Goa'uld would retreat. However, the ha'taks had been modified with Ancient shield technology by Anubis, and they overpowered Thor's ship. SG-1 went to rescue Hiemdall and Thor using a tel'tak. Anubis' Ha'tak persued them, but Freyr arrived with three O'Neill-class ships, forcing Anubis to retreat.
