Exoplanet caught in ‘hairpin turn’ signals how high-mass gas giants form - EurekAlert


Astronomers have discovered a planet that has the most oblong orbit ever found among transiting planets. The exoplanet’s extreme circuit — which looks closer to a cucumber than a circle — follows one of the most drastically stretched-out orbits of all known exoplanets, planets that orbit stars outside our solar system. It is also orbiting its star backwards, lending insight into the mystery of how close-in massive gas planets, known as hot Jupiters, form, stabilize and evolve over time.
