A Young Red Dwarf and Its Massive Imaged Companion

2MASS J16262785-2625152 is an M4.5 star located 474 light-years away. As an M-type dwarf, it is a small, cool red dwarf, and its age is 0.005 billion years, placing it among the very young stars with ages under 0.1 billion years. One planet orbits this host.

That planet is KOINTREAU-4 b, discovered in 2026 by direct imaging. No orbital period is reported for KOINTREAU-4 b. Its reported mass estimate is 4860 Earth masses, which makes it larger than Earth and roughly 15.3 times Jupiter's mass.
