TOI-4552 and Its Earth-Like Planet
TOI-4552 is a small, cool red dwarf of spectral type M4.5 V, lying 88.9 light-years away. Its mass is 0.262 solar masses, its radius is 0.287 solar radii, and its temperature is 3260 K. One planet orbits this star.
That planet, TOI-4552 b, is an Earth-like world, a class that compares radius with Earth's rather than composition. It has a radius of 1.11 Earth radii, larger than Earth's, and a mass of 1.83 Earth masses, larger than Earth's. Its mean density is 7.37 g/cm³, 1.34 times Earth's. Its orbital period is 0.301 days, and it was found by the transit method in 2026.
