KMT-2021-BLG-1077L c
KMT-2021-BLG-1077L c is a cold gas giant orbiting the M V star KMT-2021-BLG-1077L in the constellation Scorpius. It lies about 26,875 light-years from Earth and was discovered in 2022 using the microlensing method.
Is KMT-2021-BLG-1077L c in the Habitable Zone?
The position of KMT-2021-BLG-1077L c relative to the habitable zone of KMT-2021-BLG-1077L cannot be precisely determined from the available orbital data.
Orbit and Year Length
KMT-2021-BLG-1077L c orbits at an average distance of 0.930 AU — comparable to the inner Solar System.
How Was KMT-2021-BLG-1077L c Discovered?
KMT-2021-BLG-1077L c was discovered in 2022 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-1077L c?
KMT-2021-BLG-1077L c is 26,875.3 light-years (8,240.0 parsecs) from Earth. Light arriving here tonight left the planet about 26,875 years ago. A probe traveling at the speed of Voyager 1 — about 17 km/s, the fastest outbound spacecraft ever launched — would need roughly 473,005,280 years to make the journey.
