Is KOINTREAU-4 b in the Habitable Zone?
The position of KOINTREAU-4 b relative to the habitable zone of 2MASS J16262785-2625152 cannot be precisely determined from the available orbital data.
Orbit and Year Length
KOINTREAU-4 b orbits at an average distance of 182.000 AU.
How Was KOINTREAU-4 b Discovered?
KOINTREAU-4 b was discovered in 2026 using the imaging method, with observations from W. M. Keck Observatory.
Direct imaging captures actual pictures of a planet by blocking out the overwhelming glare of its host star. It works best for young, hot, massive planets on wide orbits.
How Far Away Is KOINTREAU-4 b?
KOINTREAU-4 b is 474.3 light-years (145.4 parsecs) from Earth. Light arriving here tonight left the planet around the year 1552. A probe traveling at the speed of Voyager 1 — about 17 km/s, the fastest outbound spacecraft ever launched — would need roughly 8,347,680 years to make the journey.
