About
This dataset contains detailed information on approximately 3,373 confirmed exoplanets discovered by the Kepler Telescope, including those found during Kepler's K2 mission. The Kepler Mission's primary goal is to explore the structure and variety of planetary systems by surveying a large sample of stars. This dataset is designed to support the scientific objectives of the Kepler Mission and future NASA missions by providing extensive data on these discovered exoplanets.
