A new study published in Science Advances on Wednesday, however, has added more support to the hypothesis that there is a moon orbiting one particular exoplanet. The planet is Kepler 1625b, a Jupiter-sized planet orbiting a nine-billion-year-old, sun-like star (Kepler 1625) roughly 8,000 light-years away. Artist’s impression of the exoplanet Kepler 1625b transiting the star with the potential exomoon in tow. But Kepler 1625b is far enough from the star that a moon could potentially form and also be detectable. There's also the possibility that NASA's newest exoplanet instrument, the Transiting Exoplanet Survey Satellite (TESS), will hasten the search for exomoons.
