IRAS 04125+2902 b, also known as TIDYE-1b, is an extremely young exoplanet orbiting the young protostar IRAS 04125+2902 approximately 520 light-years from Earth in the constellation of Taurus. It is the youngest transiting exoplanet so far discovered, with an age of just three million years. Over time, the planet will continue to shrink as it continues consolidating material. The planet orbits its host star closely at a distance of 0.07 AU every 8.8 days.
The discovery of the exoplanet was announced on November 20, 2024, by the use of the transit method of data from the Transiting Exoplanet Survey Satellite (TESS), with the results published in the magazine Nature. It is a potential target for analyzing its atmosphere, if it has one, by the James Webb Space Telescope since it is still young and likely has an extended atmosphere.
