NotesOne of the earliest extrasolar planets to be discovered, Draugr is also one of the least massive. It is the innermost member of a system with three solid planets, the others being Poltergeist and Phobetor, and all three follow close, rapid orbits around the pulsar known as Lich, some 2,300 light years from the Solar System.
