Using NASA’s Transiting Exoplanet Survey Satellite (TESS), an international team of astronomers has discovered an extrasolar planet orbiting TOI-4616—a nearby M-dwarf star. The newfound alien world, which received designation TOI-4616 b, is slightly larger than Earth. The finding was reported in a research paper published March 11 on the arXiv pre-print server.
Launched in 2018, TESS is in the process of scanning about 200,000 of the brightest stars near the sun, searching for potential transiting exoplanets. To date, it has identified more than 7,900 candidate exoplanets (TESS Objects of Interest, or TOI), of which 760 have been confirmed.
