Kepler-1708b

Kepler-1708b (previously known as KIC 7906827.01) is a Jupiter-sized exoplanet orbiting the Sun-like star Kepler-1708, located in the constellation of Cygnus approximately 5,600 light years away from Earth.

This mass upper limit predicts a maximum radial velocity amplitude of <98 m/s—although within reach of the most precise spectrographs available, the faintness of Kepler-1708b's host star would make observations difficult.

[9] At this distance, Kepler-1708b lies within the habitable zone of its host star, where it receives an insolation flux 0.561+0.074−0.068 times that of Earth at a relatively cool equilibrium temperature of 200–300 kelvins (−73–27 °C; −100–80 °F).

[11] The European Space Agency's Gaia satellite has measured a stellar parallax of 0.5730±0.0340 milliarcseconds (mas) and directional proper motion components of RA −0.770±0.057 mas/yr, Dec −5.005±0.059 mas/yr.
