KMT-2018-BLG-0087L b
KMT-2018-BLG-0087L b is a cold gas giant orbiting KMT-2018-BLG-0087L in the constellation Ophiuchus. It lies about 22,896 light-years from Earth and was discovered in 2022 using the microlensing method.
Is KMT-2018-BLG-0087L b in the Habitable Zone?
The position of KMT-2018-BLG-0087L b relative to the habitable zone of KMT-2018-BLG-0087L cannot be precisely determined from the available orbital data.
Orbit and Year Length
KMT-2018-BLG-0087L b orbits at an average distance of 0.870 AU — comparable to the inner Solar System.
How Was KMT-2018-BLG-0087L b Discovered?
KMT-2018-BLG-0087L 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 KMT-2018-BLG-0087L b?
KMT-2018-BLG-0087L b is 22,896.2 light-years (7,020.0 parsecs) from Earth. Light arriving here tonight left the planet about 22,896 years ago. A probe traveling at the speed of Voyager 1 — about 17 km/s, the fastest outbound spacecraft ever launched — would need roughly 402,973,120 years to make the journey.
