Is KMT-2017-BLG-1194L b in the Habitable Zone?
The position of KMT-2017-BLG-1194L b relative to the habitable zone of KMT-2017-BLG-1194L cannot be precisely determined from the available orbital data.
Orbit and Year Length
KMT-2017-BLG-1194L b orbits at an average distance of 1.780 AU.
How Was KMT-2017-BLG-1194L b Discovered?
KMT-2017-BLG-1194L b was discovered in 2023 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-2017-BLG-1194L b?
KMT-2017-BLG-1194L b is 13,829.0 light-years (4,240.0 parsecs) from Earth. Light arriving here tonight left the planet about 13,829 years ago. A probe traveling at the speed of Voyager 1 — about 17 km/s, the fastest outbound spacecraft ever launched — would need roughly 243,390,400 years to make the journey.
