The Microlensing System KMT-2017-BLG-2197L
KMT-2017-BLG-2197L is a star 25400 light-years away with a reported mass estimate of 0.36 solar masses, smaller than the Sun's. One planet orbits this host.
That planet, KMT-2017-BLG-2197L b, was discovered in 2025 by microlensing. Its reported mass estimate is 2810 Earth masses, larger than Earth's and roughly 8.84 times Jupiter's mass. Its mass is therefore substantial by any measure applied here, though ordinary estimates of this kind are not minimum masses.
No orbital period is reported for KMT-2017-BLG-2197L b, so its year remains unmeasured.
