MOA-2007-BLG-400L b
MOA-2007-BLG-400L b is a cold gas giant orbiting MOA-2007-BLG-400L in the constellation Sagittarius. It lies about 22,472 light-years from Earth and was discovered in 2008 using the microlensing method.
Is MOA-2007-BLG-400L b in the Habitable Zone?
The position of MOA-2007-BLG-400L b relative to the habitable zone of MOA-2007-BLG-400L cannot be precisely determined from the available orbital data.
Orbit and Year Length
MOA-2007-BLG-400L b orbits at an average distance of 5.900 AU.
How Was MOA-2007-BLG-400L b Discovered?
MOA-2007-BLG-400L b was discovered in 2008 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-2007-BLG-400L b?
MOA-2007-BLG-400L b is 22,472.1 light-years (6,890.0 parsecs) from Earth. Light arriving here tonight left the planet about 22,472 years ago. A probe traveling at the speed of Voyager 1 — about 17 km/s, the fastest outbound spacecraft ever launched — would need roughly 395,508,960 years to make the journey.
