TYC 1422-614-1 is an orange K-type dwarf (about 1.15 solar masses, 4,806 K, 6.85 solar radii), 672 light-years from Earth. TYC 1422-614-1 b is a 2.50-Jupiter-mass companion, with an orbital period of 198 days, at 0.690 AU from its star, on an eccentric orbit (e ≈ 0.06), discovered in 2014 via radial velocity. TYC 1422-614-1 c is a 10.0-Jupiter-mass companion, with an orbital period of 1.53 years, at 1.370 AU from its star, discovered in 2014 via radial velocity. Mutual gravitational tugs between the planets can slowly reshape their orbits, preserving clues to the system's assembly.
