Pulsar planets are planets that are orbiting pulsars. The first such planets to be discovered were around a millisecond pulsar in 1992 and were the first extrasolar planets to be confirmed as discovered. Pulsars are extremely precise clocks and even small planets can create detectable variations in pulsar traits; the smallest-known exoplanet is ...
The first pulsar with planets, PSR B1257+12; The first pulsar observed to have been affected by asteroids: PSR J0738−4042; The first double pulsar binary system, PSR J0737−3039; The shortest period pulsar, PSR J1748−2446ad, with a period of ~0.0014 seconds or ~1.4 milliseconds (716 times a second).
These were the first discovery of extrasolar planets to be confirmed; [17] [18] as pulsar planets, they surprised many astronomers who expected to find planets only around main-sequence stars. Additional uncertainty surrounded the system, because of a claim of an earlier pulsar planet around PSR 1829-10 that had to be retracted due to errors in ...
PSR B1257+12 b, alternatively designated PSR B1257+12 A, also named Draugr, is an extrasolar planet approximately 2,300 light-years (710 pc) away [4] in the constellation of Virgo. The planet is the innermost object orbiting the pulsar Lich , making it a pulsar planet in the dead stellar system.
PSR B1620-26 b orbits a pair of stars.The primary star, PSR B1620-26, is a pulsar, a neutron star spinning at 100 revolutions per second, with a mass of 1.34 M ☉, a likely radius of around 20 kilometers (0.00003 R ☉) and a likely temperature less than or equal to 300,000 K.
The pulsar was discovered by Russell Alan Hulse and Joseph Hooton Taylor Jr., of the University of Massachusetts Amherst in 1974. Their discovery of the system and analysis of it earned them the 1993 Nobel Prize in Physics "for the discovery of a new type of pulsar, a discovery that has opened up new possibilities for the study of gravitation."

PSR B1257+12 c, alternatively designated PSR B1257+12 B, also named Poltergeist, is an extrasolar planet approximately 2,300 light-years away [3] in the constellation of Virgo. It was one of the first planets ever discovered outside the Solar System , [ 4 ] [ 5 ] and is one of three pulsar planets known to be orbiting the pulsar Lich .
