DMPP-1 is a Sun-like F-type star (about 1.21 solar masses, 6,196 K, 1.26 solar radii), 62.5 light-years from Earth. DMPP-1 d is a 4.7-Earth-mass planet, with an orbital period of 3.1 days, at 0.045 AU from its star, on an eccentric orbit (e ≈ 0.36), discovered in 2019 via radial velocity. DMPP-1 e is a 4.1-Earth-mass planet, with an orbital period of 5.5 days, at 0.065 AU from its star, and an equilibrium temperature near 1,314 K, on an eccentric orbit (e ≈ 0.07), discovered in 2019 via radial velocity.
