This is a list of exoplanet discoveries that were the first by several criteria, including:
the detection method used, the planet type, the planetary system type, the star type, and others.
The first The choice of "first" depends on definition and confirmation, as below. The three systems detected prior to 1994 each have a drawback, with Gamma Cephei Ab being unconfirmed until 2002; while the PSR B1257+12 planets orbit a pulsar. This leaves 51 Pegasi b (discovered and confirmed 1995) as the first confirmed exoplanet around a non-compact star.
