Astronomers have discovered a newborn planet, IRAS 04125+2902 b (TIDYE-1b), orbiting a young star about 520 light-years away. This planet, estimated to be 10-20 times Earth’s mass, formed in just 3 million years, challenging existing theories of planetary formation, as Earth took 10-20 million years. It orbits its star every 8.8 days and is located close to it, likely after migrating inward from a farther distance.
The star, less massive and luminous than the sun, is surrounded by remnants of its protoplanetary disk, the material from which the planet formed. Detected using NASA’s TESS space telescope via the “transit” method, this is the youngest transiting planet known. The discovery reveals new insights into how quickly planets can form and survive within their protoplanetary disks.
