“ There are three known planets in the PSR B1257 system, which have been named Draugr, Poltergeist and Phobetor. Poltergeist was the first to be discovered. I know, I was curious about their names as well. Poletrgeist means pounding ghost. The draugr are the unded in Norse legends who live in their graves. And Phobetor is the personification of nightmares, and the son of Nyx, Greek goddess of the night.Astronomers are goths. ”
