Astronomers confirm youngest known exoplanet Elias 2-24 b

Astronomers have confirmed Elias 2-24 b, the youngest known exoplanet at under 1 million years old. The Jupiter-mass world sits 450 light-years away, still embedded in the gas and dust disk around its host star.

• Elias 2-24 b is under 1 million years old, a record for exoplanets
• The planet is roughly Jupiter-mass and lies 450 light-years from Earth
• It orbits about 55 times farther from its star than Earth does from the Sun
• The detection was confirmed in archival Keck observations from 2018 and 2020
