Astronomers Unveil Youngest Known Super-Earth Candidate
TL;DR Summary
NASA's Transiting Exoplanet Survey Satellite (TESS) has discovered a young exoplanet, IRAS 04125+2902 b, which is only 3 million years old and located 430 light-years away. This juvenile planet, detected through a rare parting of debris in its solar system, is the youngest found using the transit method. It has a mass up to one-third of Jupiter's but a similar diameter, suggesting an inflated atmosphere. Over time, it may evolve into a super-Earth or mini-Neptune, both common types of planets in the Milky Way.
