Planet With a 4-Hour Year! 🌍⏱️

Added: 2026-05-22

[00:00:00]A planet completes a full year in just 4 hours and 18 minutes. This rocky super-earth orbits so fast that a single year beats your entire work day. In 2017, the TESS mission spotted this rapid transit signal from a star 1,200 light-years away. Because it is tidally locked, one side faces eternal daylight while the other stays in permanent darkness. Its fast elliptical orbit likely generates intense tidal heating that could trigger volcanic activity on its surface. This world holds the record for the shortest known year of any confirmed exoplanet today. You would see your host star rise and set roughly once every 4.3 hours, making a day-night cycle twice as frequent as a year. Would you survive a year that short?
