Researchers find exoplanet that appears to be too big for its sun
This artistic rendering shows the possible view from LHS 3154b toward its low-mass star, LHS 3154. The relative sizes of the exoplanet and star are causing astronomers to reevaluate previous assumptions about planet and solar system formation. Researchers say that given its large mass, LHS 3154b likely has a composition similar to that of Neptune. Penn State
