OGLE-2011-BLG-0173L b
OGLE-2011-BLG-0173L b is a cold gas giant orbiting OGLE-2011-BLG-0173L in the constellation Sagittarius. It lies about 19,896 light-years from Earth and was discovered in 2018 using the microlensing method.
Is OGLE-2011-BLG-0173L b in the Habitable Zone?
The position of OGLE-2011-BLG-0173L b relative to the habitable zone of OGLE-2011-BLG-0173L cannot be precisely determined from the available orbital data.
Orbit and Year Length
OGLE-2011-BLG-0173L b orbits at an average distance of 8.000 AU.
How Was OGLE-2011-BLG-0173L b Discovered?
OGLE-2011-BLG-0173L b was discovered in 2018 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-0173L b?
OGLE-2011-BLG-0173L b is 19,895.5 light-years (6,100.0 parsecs) from Earth. Light arriving here tonight left the planet about 19,896 years ago. A probe traveling at the speed of Voyager 1 — about 17 km/s, the fastest outbound spacecraft ever launched — would need roughly 350,160,800 years to make the journey.
