The First Exoplanet

Discovering Distant Worlds

The first confirmed exoplanet was discovered in 1992 orbiting a pulsar named PSR B1257+12. This groundbreaking discovery opened the door to a new era in astronomy, revealing that planets exist beyond our solar system.

Exoplanets are planets that orbit stars outside our solar system. Thousands of them have been found since the first discovery, varying in size, composition, and orbital characteristics.

Significance

Studying exoplanets helps us understand planetary formation, the potential for life elsewhere, and the uniqueness of Earth. The first exoplanet was a milestone in humanity's quest to explore the cosmos.
