Astronomers may have solved the mystery of a distant exoplanet that seemingly vanished from sight, after new research suggests it was dragged off its orbit by an unseen planet.
The exoplanet designated TOI-2535 b is about 1,000 light-years away and was watched by NASA's Transiting Exoplanet Survey Satellite for seven years. The hot Jupiter completed a fast eight-point-five Earth day orbit, but its path was wobbling. It then disappeared in March. The team published its research Monday in the Astrophysical Journal Letters.
