On February 25, 2025, NASA's Transiting Exoplanet Survey Satellite (TESS) marked a significant milestone in its mission to identify exoplanets. Launched in April 2018, TESS has been instrumental in expanding our understanding of worlds beyond our solar system.
In its latest achievement, TESS has added several new exoplanets to its extensive catalog. Among these discoveries is TOI-512 b, a super-Earth transiting a K-type star. This planet, with a mass approximately 1.1% that of Jupiter and a radius about 13.74% that of Jupiter, completes an orbit around its host star every 7.19 days. Located approximately 219 light-years from Earth, TOI-512 b offers valuable insights into the diversity of planetary systems.
Another notable discovery is TOI-2015 c, a sub-Neptune-sized exoplanet with a mass around 2.8% that of Jupiter. It orbits its M-type host star every 5.58 days at a distance of 0.041 AU. Situated about 154 light-years away, TOI-2015 c contributes to our understanding of planetary formation around smaller stars.
These findings underscore TESS's ongoing success in its extended mission, which has now led to the discovery of over 4,000 exoplanets. The mission's comprehensive sky survey continues to provide invaluable data, enabling astronomers to identify and study a diverse array of exoplanets, from Earth-sized worlds in habitable zones to gas giants in close orbits.
As TESS continues its mission, the scientific community eagerly anticipates further revelations about the universe's myriad planetary systems, bringing us closer to answering fundamental questions about the potential for life beyond Earth.
