San Diego State University (SDSU) astronomers have discovered the 10th known "transiting circumbinary" exoplanet, which orbits two stars and therefore has two suns.
Astronomers discover Kepler -453b a new transiting circumbinary planet, bringing the number of such known exoplanets into double digits. A circumbinary planet orbits two stars, and like the fictional planet “Tatooine” from Star Wars, this planet has two suns in its sky. The discovery marks an important milestone and comes only four years after the first Kepler circumbinary exoplanet was detected. Once thought to be rare or even impossible, these 10 discoveries confirm that such planets are common in our galaxy.
