Is KMT-2016-BLG-2142L b in the Habitable Zone?

The position of KMT-2016-BLG-2142L b relative to the habitable zone of KMT-2016-BLG-2142L cannot be precisely determined from the available orbital data.

Orbit and Year Length

KMT-2016-BLG-2142L b orbits at an average distance of 0.830 AU — comparable to the inner Solar System.

How Was KMT-2016-BLG-2142L b Discovered?

KMT-2016-BLG-2142L b was discovered in 2018 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-2016-BLG-2142L b?

KMT-2016-BLG-2142L b is 22,863.5 light-years (7,010.0 parsecs) from Earth. Light arriving here tonight left the planet about 22,864 years ago. A probe traveling at the speed of Voyager 1 — about 17 km/s, the fastest outbound spacecraft ever launched — would need roughly 402,397,600 years to make the journey.
