What are exoplanets?

Exoplanets are worlds orbiting stars beyond our Sun. They range from rocky Earth-like bodies to gas giants larger than Jupiter, revealing the staggering diversity of the cosmos.

First confirmed discovery

In 1992, astronomers detected the first exoplanets orbiting a pulsar, a highly magnetized neutron star.

Expanding catalog

More than five thousand exoplanets are confirmed, with thousands of additional candidates awaiting validation from space agencies.
