OGLE-2018-BLG-1212L b
OGLE-2018-BLG-1212L b is a cold gas giant orbiting OGLE-2018-BLG-1212L in the constellation Sagittarius. It lies about 5,055 light-years from Earth and was discovered in 2022 using the microlensing method.
Is OGLE-2018-BLG-1212L b in the Habitable Zone?
The position of OGLE-2018-BLG-1212L b relative to the habitable zone of OGLE-2018-BLG-1212L cannot be precisely determined from the available orbital data.
Orbit and Year Length
OGLE-2018-BLG-1212L b orbits at an average distance of 1.680 AU.
How Was OGLE-2018-BLG-1212L b Discovered?
OGLE-2018-BLG-1212L b was discovered in 2022 using the microlensing method, with observations from KMTNet.
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-2018-BLG-1212L b?
OGLE-2018-BLG-1212L b is 5,055.4 light-years (1,550.0 parsecs) from Earth. Light arriving here tonight left the planet about 5,055 years ago. A probe traveling at the speed of Voyager 1 — about 17 km/s, the fastest outbound spacecraft ever launched — would need roughly 88,975,040 years to make the journey.
