===Detection of exoplanets===
The first confirmed detection of an [[exoplanet]] was in 1992, with the discovery of several terrestrial-mass planets orbiting the [[pulsar]] [[PSR B1257+12]]. The first confirmed detection of exoplanets of a [[main-sequence]] star was made in 1995, when a giant planet, [[51 Pegasi b]], was found in a four-day orbit around the nearby [[G-type star]] [[51 Pegasi]]. The frequency of detections has increased since then, particularly through advancements in [[methods of detecting extrasolar planets]] and dedicated planet-finding programs such as the [[Kepler (spacecraft)|Kepler mission]].
