OGLE-2018-BLG-1011L c
OGLE-2018-BLG-1011L c is a cold gas giant orbiting OGLE-2018-BLG-1011L in the constellation Sagittarius. It lies about 23,157 light-years from Earth and was discovered in 2019 using the microlensing method.
Is OGLE-2018-BLG-1011L c in the Habitable Zone?
The position of OGLE-2018-BLG-1011L c relative to the habitable zone of OGLE-2018-BLG-1011L cannot be precisely determined from the available orbital data.
Orbit and Year Length
OGLE-2018-BLG-1011L c orbits at an average distance of 0.800 AU — comparable to the inner Solar System.
How Was OGLE-2018-BLG-1011L c Discovered?
OGLE-2018-BLG-1011L c was discovered in 2019 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-2018-BLG-1011L c?
OGLE-2018-BLG-1011L c 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.
