Yale astronomers discover new exoplanet, size of Neptune
Astronomers at Yale University, US have discovered a new Neptune-sized planet in a solar system 3,000 light-years from Earth. The exoplanet was found in the Kepler-150 system discovered 3 years ago with 4 other planets. It was overlooked as it has a long 637-day orbit around its host star, astronomers said. The discovery was made by studying planet transit signals.
