KMT-2018-BLG-0029L b
KMT-2018-BLG-0029L b is a super-Earth orbiting KMT-2018-BLG-0029L in the constellation Ophiuchus. It lies about 11,024 light-years from Earth and was discovered in 2020 using the microlensing method.
Is KMT-2018-BLG-0029L b in the Habitable Zone?
The position of KMT-2018-BLG-0029L b relative to the habitable zone of KMT-2018-BLG-0029L cannot be precisely determined from the available orbital data.
Orbit and Year Length
KMT-2018-BLG-0029L b orbits at an average distance of 4.270 AU.
How Was KMT-2018-BLG-0029L b Discovered?
KMT-2018-BLG-0029L b was discovered in 2020 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-0029L b?
KMT-2018-BLG-0029L b is 11,024.1 light-years (3,380.0 parsecs) from Earth. Light arriving here tonight left the planet about 11,024 years ago. A probe traveling at the speed of Voyager 1 — about 17 km/s, the fastest outbound spacecraft ever launched — would need roughly 194,024,160 years to make the journey.
