Remarks

02 Oct 2018: The exo-moon Kepler-1625 b I is confirmed (Teachey & Kipping). The moon orbits the planet at about 40 RPl (Teachey & Kipping 2018).
09 Aug 2017: Kepler-1625 b I forms with Kepler-1625 b a binary planetary-mass candidate. HST observations are planed for October 29 2017 to confirm/reject it.
