OGLE-2005-BLG-071L b
OGLE-2005-BLG-071L b is a cold gas giant orbiting OGLE-2005-BLG-071L in the constellation Scorpius. It lies about 10,437 light-years from Earth and was discovered in 2005 using the microlensing method.
Is OGLE-2005-BLG-071L b in the Habitable Zone?
The position of OGLE-2005-BLG-071L b relative to the habitable zone of OGLE-2005-BLG-071L cannot be precisely determined from the available orbital data.
Temperature on OGLE-2005-BLG-071L b
The equilibrium temperature of OGLE-2005-BLG-071L b is about 55 K (-218 °C) — well below freezing. This estimate ignores any atmosphere, which could change surface temperatures dramatically — Earth's greenhouse effect adds about 33 °C.
Orbit and Year Length
OGLE-2005-BLG-071L b orbits at an average distance of 3.600 AU.
How Was OGLE-2005-BLG-071L b Discovered?
OGLE-2005-BLG-071L b was discovered in 2005 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-2005-BLG-071L b?
OGLE-2005-BLG-071L b is 10,437.0 light-years (3,200.0 parsecs) from Earth. Light arriving here tonight left the planet about 10,437 years ago. A probe traveling at the speed of Voyager 1 — about 17 km/s, the fastest outbound spacecraft ever launched — would need roughly 183,691,200 years to make the journey.
