TOI-4578 b: A Super-Earth in Transit
TOI-4578 is a star 594 light-years away with a mass of 1.08 solar masses, a radius of 0.879 solar radii, and a temperature of 5920 K. Its radius is smaller than the Sun's, while its temperature is hotter than the Sun's. One planet orbits this host.
That planet, TOI-4578 b, is a Super-Earth - a size class that reaches 2.5 times Earth's radius. It was discovered by transit in 2026, when it passed in front of its star from our viewpoint and caused a small dip in observed brightness. Its radius is 2.27 Earth radii, larger than Earth's, and it completes one orbit every 8.62 days.
