MOA-2009-BLG-387L b
MOA-2009-BLG-387L b is a cold gas giant orbiting MOA-2009-BLG-387L in the constellation Scorpius. It lies about 18,558 light-years from Earth and was discovered in 2010 using the microlensing method.
Is MOA-2009-BLG-387L b in the Habitable Zone?
The position of MOA-2009-BLG-387L b relative to the habitable zone of MOA-2009-BLG-387L cannot be precisely determined from the available orbital data.
Orbit and Year Length
A year on MOA-2009-BLG-387L b — one full orbit around MOA-2009-BLG-387L — lasts 1,980.0 Earth days, longer than an Earth year. It orbits at an average distance of 1.800 AU.
How Was MOA-2009-BLG-387L b Discovered?
MOA-2009-BLG-387L b was discovered in 2010 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-387L b?
MOA-2009-BLG-387L b is 18,558.3 light-years (5,690.0 parsecs) from Earth. Light arriving here tonight left the planet about 18,558 years ago. A probe traveling at the speed of Voyager 1 — about 17 km/s, the fastest outbound spacecraft ever launched — would need roughly 326,626,080 years to make the journey.
