MOA-2009-BLG-266L b
MOA-2009-BLG-266L b is a Neptune-like planet orbiting MOA-2009-BLG-266L in the constellation Scorpius. It lies about 9,915 light-years from Earth and was discovered in 2011 using the microlensing method.
Is MOA-2009-BLG-266L b in the Habitable Zone?
The position of MOA-2009-BLG-266L b relative to the habitable zone of MOA-2009-BLG-266L cannot be precisely determined from the available orbital data.
Orbit and Year Length
A year on MOA-2009-BLG-266L b — one full orbit around MOA-2009-BLG-266L — lasts 2,800.0 Earth days, longer than an Earth year. It orbits at an average distance of 3.200 AU.
How Was MOA-2009-BLG-266L b Discovered?
MOA-2009-BLG-266L b was discovered in 2011 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-2009-BLG-266L b?
MOA-2009-BLG-266L b is 9,915.1 light-years (3,040.0 parsecs) from Earth. Light arriving here tonight left the planet about 9,915 years ago. A probe traveling at the speed of Voyager 1 — about 17 km/s, the fastest outbound spacecraft ever launched — would need roughly 174,505,760 years to make the journey.
