Is OGLE-2007-BLG-349L AB c in the Habitable Zone?
The position of OGLE-2007-BLG-349L AB c relative to the habitable zone of OGLE-2007-BLG-349L A cannot be precisely determined from the available orbital data.
Orbit and Year Length
A year on OGLE-2007-BLG-349L AB c — one full orbit around OGLE-2007-BLG-349L A — lasts 2,557.0 Earth days, longer than an Earth year. It orbits at an average distance of 2.590 AU.
How Was OGLE-2007-BLG-349L AB c Discovered?
OGLE-2007-BLG-349L AB c was discovered in 2016 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-2007-BLG-349L AB c?
OGLE-2007-BLG-349L AB c is 9,001.9 light-years (2,760.0 parsecs) from Earth. Light arriving here tonight left the planet about 9,002 years ago. A probe traveling at the speed of Voyager 1 — about 17 km/s, the fastest outbound spacecraft ever launched — would need roughly 158,433,440 years to make the journey.
The Host Star: OGLE-2007-BLG-349L A
OGLE-2007-BLG-349L AB c is a circumbinary planet — it orbits around two stars at once, like Tatooine in Star Wars.
