KOBE-1 is an orange K-type dwarf (about 0.63 solar masses, 4,135 K, 0.62 solar radii), 24.0 light-years from Earth. KOBE-1 b is a 8.8-Earth-mass planet, with an orbital period of 8.5 days, at 0.070 AU from its star, and an equilibrium temperature near 594 K, discovered in 2025 via radial velocity. KOBE-1 c is a 12.4-Earth-mass planet, with an orbital period of 29.7 days, at 0.161 AU from its star, and an equilibrium temperature near 393 K, discovered in 2025 via radial velocity. Mutual gravitational tugs between the planets can slowly reshape their orbits, preserving clues to the system's assembly.
