Two Microlensing Planets Around a Distant Red Dwarf

KMT-2021-BLG-1077L is an M V star, a small, cool red dwarf, located 26900 light-years away. Its reported mass estimate is 0.14 solar masses, smaller than the Sun's. Two planets are known to orbit this star.

Both planets were discovered by microlensing in 2022. KMT-2021-BLG-1077L b has a reported mass estimate of 69.9 Earth masses, larger than Earth's. KMT-2021-BLG-1077L c has a reported mass estimate of 79.5 Earth masses, also larger than Earth's. Among the listed planets, KMT-2021-BLG-1077L b has the smallest reported mass and KMT-2021-BLG-1077L c has the largest.

No orbital period is reported for KMT-2021-BLG-1077L b. No orbital period is reported for KMT-2021-BLG-1077L c.
