The Kepler Space Telescope was a NASA space telescope launched in 2009 to discover Earth-sized planets orbiting other stars. It was named after astronomer Johannes Kepler, who discovered the laws of planetary motion in the 17th century.
Kepler used a technique called the transit method to find planets. This method involves looking for tiny dips in the brightness of a star that occur when a planet crosses in front of it. Kepler monitored over 100,000 stars for four years, and during that time it discovered over 2,600 exoplanets, or planets outside our solar system. Some of the most notable discoveries made by Kepler include:

Some of the most notable discoveries made by Kepler include:
- Kepler-186f, the first Earth-sized planet to be found in the habitable zone of another star. This means that the planet is the right distance from its star to potentially support liquid water on its surface.
- Kepler-452b, the first Earth-sized planet to be found orbiting in the habitable zone of a sun-like star. This means that the planet is very similar to Earth in terms of its size and orbit, and it could potentially be habitable.
- Kepler-62e and Kepler-62f, two Earth-sized planets orbiting in the habitable zone of a star that is smaller and cooler than the Sun. These planets could potentially be habitable, and they are some of the most Earth-like planets yet discovered.
