KMT-2018-BLG-0748L b
KMT-2018-BLG-0748L b is a cold gas giant orbiting KMT-2018-BLG-0748L in the constellation Scorpius. It lies about 23,809 light-years from Earth and was discovered in 2020 using the microlensing method.
Is KMT-2018-BLG-0748L b in the Habitable Zone?
The position of KMT-2018-BLG-0748L b relative to the habitable zone of KMT-2018-BLG-0748L cannot be precisely determined from the available orbital data.
Orbit and Year Length
KMT-2018-BLG-0748L b orbits at an average distance of 0.620 AU — comparable to the inner Solar System.
How Was KMT-2018-BLG-0748L b Discovered?
KMT-2018-BLG-0748L 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-0748L b?
KMT-2018-BLG-0748L b is 23,809.4 light-years (7,300.0 parsecs) from Earth. Light arriving here tonight left the planet about 23,809 years ago. A probe traveling at the speed of Voyager 1 — about 17 km/s, the fastest outbound spacecraft ever launched — would need roughly 419,045,440 years to make the journey.
