K2-2016-BLG-0005Lb

K2-2016-BLG-0005Lb is the most distant exoplanet discovered by the Kepler space telescope, it is the most distant world ever captured by the planet-hunting observatory, twice the distance of its previous record. Its distance is estimated at 16960 light years from the Earth, it was discovered on January 4, 2022 thanks to an effect of gravitational microlensing from a series of data recorded in 2016, then revealed on March 31, 2022.[1][2]

    Star

    K2-2016-BLG-0005Lb orbits a dwarf star less massive than the Sun, named K2-2016-BLG-0005L. Its mass is estimated at 0.584 ± 0.03 solar mass.[1][2]

    Planet

    The exoplanet is almost an exact twin of Jupiter. It is of similar mass and orbits at almost the same orbital distance. The power of the gravitational lens allowed the team to determine that the exoplanet is about 1.1 Jovian mass, orbiting its star at a circular distance of 4.18 ± 0, 27 astronomical units, the average orbital distance of Jupiter being 5.2 astronomical units.[1][2]
