"Astronomers Discover 'Cold Saturn' with Unusually Long Year"

NASA's TESS has discovered two giant planets, TOI-4600 b and c, orbiting a star 700 light-years away, with the outer planet having the longest year of 483 days and being among the coldest exoplanets found so far. These planets could provide valuable insights into the formation and evolution of large, gaseous planets, filling a gap in knowledge between gas giants like Jupiter and "hot Jupiters." While space telescopes have been able to measure some atmospheric components of hot and warm Jupiters, TOI-4600 b and c offer the rarer prospect of revealing atmospheric ingredients of "temperate" gas giants.

TESS Discovers Longest-Orbit Exoplanet in NASA's Latest Findings

Astronomers using NASA's Transiting Exoplanet Survey Satellite (TESS) have discovered a rare system containing two long-period planets orbiting the star TOI-4600, located 815 light years away from Earth. The inner planet has an 82-day orbit, similar to Mercury, while the outer planet has a 482-day orbit, placing it between Earth and Mars. These gas giants bridge the gap between "hot Jupiters" and the colder, longer-period gas giants in our solar system. The discovery provides valuable insights into the formation and composition of planets with longer orbital periods.

TESS mission uncovers planet with record-breaking orbit

Astronomers using NASA's TESS mission have discovered a rare system containing two long-period planets orbiting the star TOI-4600, located 815 light years from Earth. The inner planet has an 82-day orbit, similar to Mercury, while the outer planet has a 482-day orbit, placing it between Earth and Mars. Both planets are likely gas giants, bridging the gap between "hot Jupiters" and the colder, longer-period gas giants in our solar system. The discovery provides valuable insights into the formation and composition of planets with longer orbital periods.
