XEST 17-036 and Its Young World
XEST 17-036 is a star 517 light-years away with a spectral type of M4, placing it among the small, cool red dwarfs. Its reported mass of 0.26 solar masses is smaller than the Sun's, and its temperature of 3550 K is cooler than the Sun's. At 0.0033 billion years old, it is a very young star. One planet is known to orbit this host.
That planet, KOINTREAU-1 b, was found by imaging in 2026. Its reported mass of 3370 Earth masses is larger than Earth's and roughly 10.6 times Jupiter's mass. No orbital period is reported for KOINTREAU-1 b.
