This planet celebrates new year every 21 hours
India TodayAstronomers have discovered a rare type of planet outside Solar System where a year lasts just 21 hours. TOI-3261 b, an ultra-hot Neptune-sized planet, has become the latest addition to an elite group of celestial bodies that defy conventional theories of planetary evolution. Their paper, "Surviving in the Hot Neptune Desert: The Discovery of the Ultrahot Neptune TOI-3261 b," details this extraordinary planetary system. This loss occurred through two primary mechanisms: photoevaporation, where stellar energy causes gas particles to dissipate, and tidal stripping, where the star's gravity pulls away layers of the planet's atmosphere. This characteristic provides a unique opportunity for further study, potentially using Nasa's James Webb Space Telescope to analyze the planet's atmosphere in infrared light.
