International Planet Hunters Discover Dozens of Strange New Worlds

The NASA TESS-Keck Survey provides details on the mass and density of 126 planets.
Although thousands of planets have been discovered orbiting other stars, our understanding of them remains limited. A NASA catalog featuring 126 newly discovered exotic worlds provides detailed measurements, enabling comparisons with our own solar system.

The catalog details a fascinating mix of planet types beyond our solar system, from rare worlds with extreme environments to ones that could possibly support life.

The planets were analyzed by a large, international team of scientists using NASA’s Transiting Exoplanet Survey Satellite (TESS) in collaboration with the W.M. Keck Observatory on Maunakea, Hawai’i. They are described in a recent edition of The Astrophysical Journal Supplement.
