Kepler-1625 is a star in the constellation Swan , of about 8,000 light-years from the sun away. It is orbited by at least one exoplanet , which in turn may be accompanied by an exomoon . Kepler-1625 has an apparent magnitude of only around 14 mag (K-band) and can therefore not be observed with the naked eye.

Planetary system

Based on observations of the star by the Kepler space telescope using the transit method , the discovery of a planet around Kepler-1625, called Kepler-1625b , was announced in 2016 . According to studies published in 2017, the approximately Jupiter-sized planet may be orbited by a Neptune-sized moon .
