KMT-2021-BLG-0712L b is a Neptune-like planet orbiting KMT-2021-BLG-0712L in the constellation Scorpius. It lies about 10,078 light-years from Earth and was discovered in 2023 using the microlensing method.
Is KMT-2021-BLG-0712L b in the Habitable Zone?
The position of KMT-2021-BLG-0712L b relative to the habitable zone of KMT-2021-BLG-0712L cannot be precisely determined from the available orbital data.
Orbit and Year Length
KMT-2021-BLG-0712L b orbits at an average distance of 2.220 AU.
How Was KMT-2021-BLG-0712L b Discovered?
KMT-2021-BLG-0712L b was discovered in 2023 using the microlensing method, with observations from KMTNet.
Gravitational microlensing detects a planet when its host star passes in front of a more distant background star, and the planet's gravity adds a brief, telltale spike to the magnified starlight. It can find planets thousands of light-years away.
How Far Away Is KMT-2021-BLG-0712L b?
KMT-2021-BLG-0712L b is 10,078.2 light-years (3,090.0 parsecs) from Earth. Light arriving here tonight left the planet about 10,078 years ago. A probe traveling at the speed of Voyager 1 — about 17 km/s, the fastest outbound spacecraft ever launched — would need roughly 177,376,320 years to make the journey.
