MOA-bin-29 b
MOA-bin-29 b is a cold gas giant orbiting MOA-bin-29 in the constellation Sagittarius. It lies about 23,222 light-years from Earth and was discovered in 2019 using the microlensing method.
Is MOA-bin-29 b in the Habitable Zone?
The position of MOA-bin-29 b relative to the habitable zone of MOA-bin-29 cannot be precisely determined from the available orbital data.
Orbit and Year Length
MOA-bin-29 b orbits at an average distance of 0.480 AU — comparable to the inner Solar System.
How Was MOA-bin-29 b Discovered?
MOA-bin-29 b was discovered in 2019 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-bin-29 b?
MOA-bin-29 b is 23,222.3 light-years (7,120.0 parsecs) from Earth. Light arriving here tonight left the planet about 23,222 years ago. A probe traveling at the speed of Voyager 1 — about 17 km/s, the fastest outbound spacecraft ever launched — would need roughly 408,712,480 years to make the journey.
