OGLE-2011-BLG-0251L b
OGLE-2011-BLG-0251L b is a cold gas giant orbiting the M star OGLE-2011-BLG-0251L in the constellation Ophiuchus. It lies about 8,382 light-years from Earth and was discovered in 2012 using the microlensing method.
Is OGLE-2011-BLG-0251L b in the Habitable Zone?
The position of OGLE-2011-BLG-0251L b relative to the habitable zone of OGLE-2011-BLG-0251L cannot be precisely determined from the available orbital data.
Orbit and Year Length
OGLE-2011-BLG-0251L b orbits at an average distance of 2.720 AU.
How Was OGLE-2011-BLG-0251L b Discovered?
OGLE-2011-BLG-0251L b was discovered in 2012 using the microlensing method, with observations from OGLE.
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 OGLE-2011-BLG-0251L b?
OGLE-2011-BLG-0251L b is 8,382.2 light-years (2,570.0 parsecs) from Earth. Light arriving here tonight left the planet about 8,382 years ago. A probe traveling at the speed of Voyager 1 — about 17 km/s, the fastest outbound spacecraft ever launched — would need roughly 147,526,720 years to make the journey.
