Is KMT-2023-BLG-0084L b in the Habitable Zone?

The position of KMT-2023-BLG-0084L b relative to the habitable zone of KMT-2023-BLG-0084L cannot be precisely determined from the available orbital data.

Orbit and Year Length

KMT-2023-BLG-0084L b orbits at an average distance of 2.500 AU.

How Was KMT-2023-BLG-0084L b Discovered?

KMT-2023-BLG-0084L b was discovered in 2026 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-2023-BLG-0084L b?

KMT-2023-BLG-0084L b is 13,046.2 light-years (4,000.0 parsecs) from Earth. Light arriving here tonight left the planet about 13,046 years ago. A probe traveling at the speed of Voyager 1 — about 17 km/s, the fastest outbound spacecraft ever launched — would need roughly 229,613,120 years to make the journey.
