When were the first extrasolar planets discovered?

The first extrasolar planets were discovered in 1992. These planets were found orbiting the pulsar known as PSR 1257+12 using the pulsation timing method, which detects variations in the arrival times of radio pulses.12

While the 1992 discovery marks the first detection of extrasolar planets, the 1995 discovery of 51 Pegasi b by Michel Mayor and Didier Queloz is also highly significant, as it was the first planet confirmed to orbit a sunlike star. Mayor and Queloz utilized the radial velocity method to identify this planet, a breakthrough for which they were awarded the 2019 Nobel Prize in Physics.31
