KMT-2017-BLG-0428L and Its Planet

KMT-2017-BLG-0428L is a host star located 17,600 light-years away, and it has one known planet in orbit around it. The star's reported mass estimate is 0.34 solar masses, which is smaller than the Sun's.

The planet is named KMT-2017-BLG-0428L b. It was discovered in 2023 using microlensing, a method that detects a planet when its gravity briefly brightens the light of a more distant background star. No orbital period is reported for KMT-2017-BLG-0428L b, so the time it takes to complete one orbit is unknown.

KMT-2017-BLG-0428L b has a reported mass estimate of 5.59 Earth masses. That estimate is larger than Earth's, placing the planet in a mass range well above our own world's.
