MOA-2015-BLG-337L b
MOA-2015-BLG-337L b is a Neptune-like planet orbiting MOA-2015-BLG-337L in the constellation Sagittarius. It lies about 23,157 light-years from Earth and was discovered in 2018 using the microlensing method.
Is MOA-2015-BLG-337L b in the Habitable Zone?
The position of MOA-2015-BLG-337L b relative to the habitable zone of MOA-2015-BLG-337L cannot be precisely determined from the available orbital data.
Orbit and Year Length
MOA-2015-BLG-337L b orbits at an average distance of 0.240 AU — closer to its star than Mercury is to the Sun.
How Was MOA-2015-BLG-337L b Discovered?
MOA-2015-BLG-337L b was discovered in 2018 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-2015-BLG-337L b?
MOA-2015-BLG-337L b is 23,157.1 light-years (7,100.0 parsecs) from Earth. Light arriving here tonight left the planet about 23,157 years ago. A probe traveling at the speed of Voyager 1 — about 17 km/s, the fastest outbound spacecraft ever launched — would need roughly 407,564,960 years to make the journey.
