Is OGLE-2017-BLG-1237L b in the Habitable Zone?

The position of OGLE-2017-BLG-1237L b relative to the habitable zone of OGLE-2017-BLG-1237L cannot be precisely determined from the available orbital data.

Orbit and Year Length

OGLE-2017-BLG-1237L b orbits at an average distance of 2.530 AU.

How Was OGLE-2017-BLG-1237L b Discovered?

OGLE-2017-BLG-1237L b was discovered in 2024 using the microlensing method, with observations from OGLE.

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 OGLE-2017-BLG-1237L b?

OGLE-2017-BLG-1237L b is 19,667.2 light-years (6,030.0 parsecs) from Earth. Light arriving here tonight left the planet about 19,667 years ago. A probe traveling at the speed of Voyager 1 — about 17 km/s, the fastest outbound spacecraft ever launched — would need roughly 346,142,720 years to make the journey.
