KMT-2025-BLG-1616L b
KMT-2025-BLG-1616L b is a Neptune-like planet orbiting the M V star KMT-2025-BLG-1616L in the constellation Scorpius. It lies about 24,462 light-years from Earth and was discovered in 2026 using the microlensing method.
Is KMT-2025-BLG-1616L b in the Habitable Zone?
The position of KMT-2025-BLG-1616L b relative to the habitable zone of KMT-2025-BLG-1616L cannot be precisely determined from the available orbital data.
Orbit and Year Length
KMT-2025-BLG-1616L b orbits at an average distance of 1.600 AU.
How Was KMT-2025-BLG-1616L b Discovered?
KMT-2025-BLG-1616L 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-1616L b?
KMT-2025-BLG-1616L b is 24,461.7 light-years (7,500.0 parsecs) from Earth. Light arriving here tonight left the planet about 24,462 years ago. A probe traveling at the speed of Voyager 1 — about 17 km/s, the fastest outbound spacecraft ever launched — would need roughly 430,525,920 years to make the journey.
