Exoplanets are planets outside our solar system.

They orbit stars other than the Sun.

Can be similar to Earth, gas giants like Jupiter, or smaller rocky planets.

Help scientists study planet formation and potential for life beyond Earth.

Discovered using methods like the transit method (planet passes in front of star) and the radial velocity method (star’s wobble due to planet’s gravity).

Thousands of exoplanets have been found in recent years, expanding our understanding of the universe.
