MEarth Array Confirms Youngest Transiting Exoplanet

K2-33 b, shown in this illustration, is one of the youngest exoplanets detected to date and makes a complete orbit around its star in about five days. These two characteristics combined provide new constraints for planet formation theories. K2-33 b could have formed farther out and quickly migrated inward. Alternatively, it could have formed in situ, or in place.

The K2-33 system and its planet in comparison to our own solar system. The planet is on a five-day orbit, whereas Mercury orbits our Sun in 88 days. The planet is also nearly ten times closer to its star than Mercury is to the Sun.
