This is thelist of 20extrasolar planets that weredetected by timing –– 8 bypulsar timing and 12 byvariable star timing, sorted by orbital periods. It works by detecting the changes in radio emissions from pulsars caused by the gravity of orbiting planets. Same thing works for variable stars, not by radio but light.

The most massive planet detected by timing isHW Virginis b, which masses 19.2 M_J; the least massive planet isPSR B1257+12 b, which masses 0.00007 M_J or 0.022 M_🜨. The longest period of any planets detected by timing isPSR B1620-26 b, which is 36525 days or 100 years; the shortest period isSDSS J1228+1040 b, which is 0.0857 days.

There are 9 members ofmulti-planet systems, including three orbiting aroundPSR B1257+12.
