KMT-2017-BLG-0165L b is a Neptune-like planet orbiting KMT-2017-BLG-0165L in the constellation Sagittarius. It lies about 14,775 light-years from Earth and was discovered in 2018 using the microlensing method.
Is KMT-2017-BLG-0165L b in the Habitable Zone?
The position of KMT-2017-BLG-0165L b relative to the habitable zone of KMT-2017-BLG-0165L cannot be precisely determined from the available orbital data.
Orbit and Year Length
KMT-2017-BLG-0165L b orbits at an average distance of 3.450 AU.
How Was KMT-2017-BLG-0165L b Discovered?
KMT-2017-BLG-0165L 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-2017-BLG-0165L b?
KMT-2017-BLG-0165L b is 14,774.9 light-years (4,530.0 parsecs) from Earth. Light arriving here tonight left the planet about 14,775 years ago. A probe traveling at the speed of Voyager 1 — about 17 km/s, the fastest outbound spacecraft ever launched — would need roughly 260,038,240 years to make the journey.
