KMT-2025-BLG-2272L b is a cold gas giant orbiting KMT-2025-BLG-2272L in the constellation Sagittarius. It lies about 21,592 light-years from Earth and was discovered in 2026 using the microlensing method.
Is KMT-2025-BLG-2272L b in the Habitable Zone?
The position of KMT-2025-BLG-2272L b relative to the habitable zone of KMT-2025-BLG-2272L cannot be precisely determined from the available orbital data.
Orbit and Year Length
KMT-2025-BLG-2272L b orbits at an average distance of 3.890 AU.
How Was KMT-2025-BLG-2272L b Discovered?
KMT-2025-BLG-2272L 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-2025-BLG-2272L b?
KMT-2025-BLG-2272L b is 21,591.5 light-years (6,620.0 parsecs) from Earth. Light arriving here tonight left the planet about 21,592 years ago. A probe traveling at the speed of Voyager 1 — about 17 km/s, the fastest outbound spacecraft ever launched — would need roughly 380,010,400 years to make the journey.
