MOA-2010-BLG-117L b
MOA-2010-BLG-117L b is a cold gas giant orbiting MOA-2010-BLG-117L in the constellation Sagittarius. It lies about 11,416 light-years from Earth and was discovered in 2018 using the microlensing method.
Is MOA-2010-BLG-117L b in the Habitable Zone?
The position of MOA-2010-BLG-117L b relative to the habitable zone of MOA-2010-BLG-117L cannot be precisely determined from the available orbital data.
Orbit and Year Length
MOA-2010-BLG-117L b orbits at an average distance of 2.420 AU.
How Was MOA-2010-BLG-117L b Discovered?
MOA-2010-BLG-117L b was discovered in 2018 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-2010-BLG-117L b?
MOA-2010-BLG-117L b is 11,415.5 light-years (3,500.0 parsecs) from Earth. Light arriving here tonight left the planet about 11,416 years ago. A probe traveling at the speed of Voyager 1 — about 17 km/s, the fastest outbound spacecraft ever launched — would need roughly 200,912,800 years to make the journey.
