This is the list of 16 extrasolar planets that were detected by timing –– 5 by pulsar timing and 11 by variable star timing, sorted by orbital periods. It works by much the radio emissions emitted from pulsars changed cause by the gravity of orbiting planets. Same thing works for variable stars, not by radio but light.

The most massive planet detected by timing is HW Virginis b, which masses 19.2 MJ; the least massive planet is PSR B1257+12 b, which masses 0.00007 MJ or 0.022 M. The longest period of any planets detected by timing is PSR B1620-26 b, which is 36525 days or 100 years; the shortest period is PSR B1719-14 b, which is 0.090706293 days or 2 hours, 10 minutes and 37.024 seconds.

There are 9 members of the multi-planet systems, including three orbiting around PSR B1257+12.
