PSR B1257+12 b
Innermost planet of the pulsar Lich, one of the first exoplanets ever found.
PSR B1257+12 b, named Draugr, is the innermost of three planets orbiting the millisecond pulsar PSR B1257+12 (named Lich), about 2,300 light-years away in Virgo. The pulsar planets around it were the first planets found outside the Solar System and the first pulsar planets: two were found in 1992 and Draugr followed in 1994.
Draugr is the lowest-mass planet found by any method so far, with a little less than twice the mass of Earth's Moon.
