Any planet outside our solar system is considered an exoplanet.

Although their existence had long been theorised in both research labs and in popular culture—think "Star Wars"—until 1995 no one had been able to prove one existed.

By setting their telescopic sights on the Sun-like star 51 Pegasi, part of the Pegasus constellation, Mayor and Queloz found it was wobbling—the light it emitted was blue as it moved toward them and red as it moved away.

That proved something was circling the star, even though they couldn't see it directly, being some 50 light years from Earth.

Nonetheless they could confirm the planet was gaseous and as big as Jupiter, yet very close to its star—it had a four-day orbit—and very hot, confounding theories on what types of celestial bodies would revolve where.
