Phobetor is the outermost of the three known planets of Lich, but all three pursue extremely close orbits around the pulsar. Phobetor's orbital distance is 0.46 AU, less than half the distance from the Sun to Earth, and it completes this orbit in less than one hundred days. Physically the planet is of the type known as a 'super Earth'; Phobetor appears to be a solid body, but has 1.5 times the Earth'sdiameter, and nearly four times its mass.
Because Phobetor was one of the first confirmed extrasolar planets to be discovered, it was designated before formal naming rules had been established, and so it was initially classified as 'PSR B1257+12 C', where 'C' indicated that it was the third planet of the pulsar. By the now standard method of designation, Phobetor is instead catalogued as 'PSR B1257+12 d'. It gained the name Phobetor (referring a mythical creature said to appear in beastly form during nightmares) in 2015, as part of public vote on naming certain important extrasolar planets.
