Scientists have identified a gas giant exoplanet, AT2021uey b, located far from the galactic center. This discovery marks only the third of its kind in astronomical history. The findings were published in the journal Astronomy & Astrophysics.
The exoplanet was found using the gravitational microlensing technique. This method involves observing how the light from a distant star is amplified by a massive object in the foreground. AT2021uey b is approximately 3,262 light-years away and has a mass 1.3 times that of Jupiter.
The planet orbits an M dwarf star, completing one orbit every 4,170 days. This discovery, made far from the galactic center, provides valuable insights into exoplanet distribution and formation. The research team continues to analyze data to learn more about exoplanets in the galactic halo.
