Scientists Reveal Extensive Catalog of 126 Newly Discovered Exoplanets

The NASA-led TESS-Keck Survey provides detailed measurements of diverse alien worlds, enhancing our understanding of planetary systems.

The catalog includes 120 confirmed exoplanets and six candidates, analyzed over three years using TESS and the W. M. Keck Observatory.
Key findings include planets with extreme environments, such as a super-Earth with a 12-hour orbit and a dense sub-Neptune nearly 19 times Earth's mass.
The catalog aims to compare these exoplanets with our solar system, offering insights into planetary formation and potential habitability.
Researchers used radial velocity measurements to determine the mass and properties of the planets, observing the 'wobble' of their host stars.
The survey highlights the diversity of planetary systems, with some planets orbiting stars similar to our sun and others around very different stars.
