MOA-2022-BLG-033L b
MOA-2022-BLG-033L b is a Neptune-like planet orbiting the F7 V star MOA-2022-BLG-033L in the constellation Sagittarius. It lies about 6,001 light-years from Earth and was discovered in 2025 using the microlensing method.
Is MOA-2022-BLG-033L b in the Habitable Zone?
The position of MOA-2022-BLG-033L b relative to the habitable zone of MOA-2022-BLG-033L cannot be precisely determined from the available orbital data.
Orbit and Year Length
MOA-2022-BLG-033L b orbits at an average distance of 2.150 AU.
How Was MOA-2022-BLG-033L b Discovered?
MOA-2022-BLG-033L 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-033L b?
MOA-2022-BLG-033L b is 6,001.3 light-years (1,840.0 parsecs) from Earth. Light arriving here tonight left the planet about 6,001 years ago. A probe traveling at the speed of Voyager 1 — about 17 km/s, the fastest outbound spacecraft ever launched — would need roughly 105,622,880 years to make the journey.
