Exoplanet Orbits Youthful Star (IMAGE)
Caption
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 exciting new directions for planet-formation theories. K2-33 b could have formed on a farther out orbit and quickly migrated inward. Alternatively, it could have formed in situ, or in place.
