TOI-128 and Its Super-Earth
TOI-128 is a star 223 light-years away with one known planet in orbit. The host star has a mass of 1.13 solar masses and a radius of 1.13 solar radii, and its temperature is 6060 K. Its reported radius estimate is larger than the Sun's, and its reported temperature is hotter than the Sun's.
The planet TOI-128.01 is classified as a Super-Earth, meaning its radius stays within 2.5 times Earth's. It was discovered in 2024 by the transit method, in which a planet passes in front of its star from our viewpoint and causes a small dip in observed brightness. The planet's orbital period is 4.94 days, and its radius is 2.22 Earth radii, larger than Earth's.
