MOA-2020-BLG-108L b
MOA-2020-BLG-108L b is a cold gas giant orbiting MOA-2020-BLG-108L in the constellation Sagittarius. It lies about 16,732 light-years from Earth and was discovered in 2026 using the microlensing method.
Is MOA-2020-BLG-108L b in the Habitable Zone?
The position of MOA-2020-BLG-108L b relative to the habitable zone of MOA-2020-BLG-108L cannot be precisely determined from the available orbital data.
Orbit and Year Length
MOA-2020-BLG-108L b orbits at an average distance of 3.690 AU.
How Was MOA-2020-BLG-108L b Discovered?
MOA-2020-BLG-108L b was discovered in 2026 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-2020-BLG-108L b?
MOA-2020-BLG-108L b is 16,731.8 light-years (5,130.0 parsecs) from Earth. Light arriving here tonight left the planet about 16,732 years ago. A probe traveling at the speed of Voyager 1 — about 17 km/s, the fastest outbound spacecraft ever launched — would need roughly 294,479,680 years to make the journey.
