NASA’s TESS Discovers a “Cold Saturn” With a Long Year

Its also amongst the coldest.Astronomical SignificanceThe two planets, TOI-4600 b and c, might show crucial to astronomers who investigate how large, gaseous planets evolve and form. Still, in a research study released in September 2023, a global group of scientists utilizing TESS data figured out that TOI-4600 b and c have long-period orbits: 83 days for world b, 483 for world c (a year thats a bit longer than Earths). Thats amongst the coldest exoplanets TESS has actually discovered so far.A global group led by astronomer Ismael Mireles of the University of New Mexico published their paper on the two worlds, “TOI-4600 b and c: Two Long-period Giant Planets Orbiting an Early K Dwarf,” in The Astrophysical Journal Letters in September 2023.
