Kepler-1625b is a super-Jupiter exoplanet orbiting the Sun-like star Kepler-1625 about 2,500 parsecs (8,200 light-years) away in the constellation of Cygnus.[2] The large gas giant is approximately the same radius as Jupiter,[3] and orbits its star every 287.4 days.[4] In 2017, hints of a Neptune-sized exomoon in orbit of the planet was found using photometric observations collected by the Kepler Mission.[5][6] Further evidence for a Neptunian moon was found the following year using the Hubble Space Telescope, where two independent lines of evidence constrained the mass and radius to be Neptune-like.[3] The mass-signature has been independently recovered by two other teams.[7][8] However, the radius-signature was independently recovered by one of the teams[8] but not the other.[7] The original discovery team later showed that this latter study appears affected by systematic error sources that may influence their findings.[9]
