MOA-2022-BLG-091L b
MOA-2022-BLG-091L b is a cold gas giant orbiting the G8 V star MOA-2022-BLG-091L in the constellation Scorpius. It lies about 13,862 light-years from Earth and was discovered in 2025 using the microlensing method.
Is MOA-2022-BLG-091L b in the Habitable Zone?
The position of MOA-2022-BLG-091L b relative to the habitable zone of MOA-2022-BLG-091L cannot be precisely determined from the available orbital data.
Orbit and Year Length
MOA-2022-BLG-091L b orbits at an average distance of 3.440 AU.
How Was MOA-2022-BLG-091L b Discovered?
MOA-2022-BLG-091L b was discovered in 2025 using the microlensing method, with observations from MOA.
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 MOA-2022-BLG-091L b?
MOA-2022-BLG-091L b is 13,861.6 light-years (4,250.0 parsecs) from Earth. Light arriving here tonight left the planet about 13,862 years ago. A probe traveling at the speed of Voyager 1 — about 17 km/s, the fastest outbound spacecraft ever launched — would need roughly 243,964,160 years to make the journey.
