Exoplanet Kepler-1658b spiralling to doom around aging star: Study

• By Staff Writer

Astronomers have found that exoplanet Kepler-1658b's orbit is decaying around an evolved, or older, host star and it appears to be spiralling closer to its maturing star until collision and ultimate obliteration. Its orbital period is decreasing at the rate of about 131 milliseconds per year. The main cause of the decay is tides, Harvard-Smithsonian Center for Astrophysics said.
