HR 858 b orbits the star HR 858 and was spotted by the keen eyes of NASA’s Transiting Exoplanet Survey Satellite (TESS) back in 2019. This space-based planet-hunter uses a high-tech CCD array to catch the tiny dips in starlight when a planet like HR 858 b passes in front of its star—a cosmic game of hide-and-seek! While details about this world are still unfolding, its discovery by the transit method hints it’s in a cozy orbit, regularly crossing its star’s face from our viewpoint. HR 858 b adds to the exciting growing family of exoplanets ushering in a new era of space exploration, reminding us how much wonder is just a little light-year’s reach away.
