Exoplanet
Planet outside of the Solar System
An exoplanet or extrasolar planet is a planet outside of the Solar System. The first confirmed detection of an exoplanet was in 1992 around a pulsar, and the first detection around a main-sequence star was in 1995. A different planet, first detected in 1988, was confirmed in…Source: Wikipedia (CC BY-SA)
Main sequence
Continuous band of stars that appears on plots of stellar color versus brightness
