According to the paper, a transit signal has been detected in the light curve of TOI-2431\u2014a star of spectral type KV7 located some 117 light years away. The planetary nature of this signal was confirmed by follow-up ground-based observations.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Using the Transiting Exoplanet Survey Satellite (TESS), an international team of astronomers has detected a new exoplanet orbiting a nearby star.
