OGLE-2017-BLG-0406L b
OGLE-2017-BLG-0406L b is a cold gas giant orbiting OGLE-2017-BLG-0406L in the constellation Sagittarius. It lies about 16,960 light-years from Earth and was discovered in 2020 using the microlensing method.
Is OGLE-2017-BLG-0406L b in the Habitable Zone?
The position of OGLE-2017-BLG-0406L b relative to the habitable zone of OGLE-2017-BLG-0406L cannot be precisely determined from the available orbital data.
Orbit and Year Length
OGLE-2017-BLG-0406L b orbits at an average distance of 3.500 AU.
How Was OGLE-2017-BLG-0406L b Discovered?
OGLE-2017-BLG-0406L b was discovered in 2020 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-2017-BLG-0406L b?
OGLE-2017-BLG-0406L b is 16,960.1 light-years (5,200.0 parsecs) from Earth. Light arriving here tonight left the planet about 16,960 years ago. A probe traveling at the speed of Voyager 1 — about 17 km/s, the fastest outbound spacecraft ever launched — would need roughly 298,497,760 years to make the journey.
