PSR B1257+12 b, along with fellow doomed worlds, were among the first and creepiest to be discovered as they orbit an undead star known as a pulsar. Pulsar planets like Poltergeist and its neighboring worlds, Phobetor and Draugr, are consumed with constant radiation from the star’s core. Nothing but the undead can subsist in this most inhospitable corner of the galaxy.

PSR B1257+12 b is a terrestrial exoplanet that orbits a pulsar. Its mass is 0.02 Earths, it takes 25.3 days to complete one orbit of its star, and is 0.19 AU from its star. Its discovery was announced in 1994.
