Researchers from Penn State University have discovered a planet that is much bigger than expected, orbiting a star that is much smaller than the sun. The planet is more than 13 times more massive than Earth, and it’s orbiting a star that is nine times less massive than the sun. This discovery goes against current theories of planet formation around small stars. The discovery was made using a new instrument called the Habitable Zone Planet Finder (HPF) at the McDonald Observatory in Texas. The discovery is challenging current understanding of how planets and stars are formed. The researchers believe that the planet’s discovery will help to better understand how the most common stars in our galaxy form planets. The paper was funded by several organizations including the National Aeronautics and Space Administration, the National Science Foundation and the Heising-Simons Foundation. The researchers plan to further study the planet and its star in order to gain a better understanding of planet formation.
