Astronomers Confirm Super-Earth TOI-1846 b Just 154 Light-Years Away
\n………………<\/p>\n
A new study published on arXiv confirms the discovery of TOI\u20111846 b, a super-Earth located 154 light-years away in the constellation Lyra. Detected by NASA\u2019s Transiting Exoplanet Survey Satellite (TESS), the planet was validated by an international team led by Abderahmane Soubkiou at Morocco\u2019s Oukaimeden Observatory.<\/p>\n
TOI\u20111846 b orbits a small red dwarf star about 40% the size of our Sun, circling it every four days. The planet is nearly twice Earth\u2019s diameter and four times its mass, suggesting a mix of dense ice and a thin atmosphere, with a surface temperature around 600\u00b0F.<\/p>\n
Its position on the so-called \u201cradius valley\u201d between rocky super-Earths and gas-rich sub-Neptunes makes it a valuable target for studying how planets form and lose their primordial gases. Astronomers plan to use infrared telescopes and instruments like MAROON\u2011X in Hawai\u2018i to measure its mass and search for additional planets.<\/p>\n
Future observations, possibly with the James Webb Space Telescope, could detect signs of water vapor or other molecules, deepening understanding of how atmospheres evolve around red dwarfs, which make up most stars in our galaxy.<\/p>\n","protected":false},"excerpt":{"rendered":"
