3 newly discovered worlds risk doom orbiting too close to dying stars

Astronomers have spotted three new exoplanets orbiting dangerously close to their parent stars, on the brink of extinction. 

The three exoplanets, named TOI-2337b, TOI-4329b and TOI-2669b, were discovered using NASA’s Transiting Exoplanet Survey Satellite (TESS) and the W. M. Keck Observatory’s High-Resolution Echelle Spectrometer (HIRES) in Hawaiʻi.
