TOI-2194 and Its Super-Earth
TOI-2194 is a star 63.8 light-years away with a mass of 0.74 solar masses, a radius of 0.691 solar radii, and a temperature of 4760 K. Its mass, radius, and temperature are all smaller or cooler than the Sun's corresponding values.
One planet orbits this star, TOI-2194 b. It is a Super-Earth, meaning its radius is larger than Earth's but does not exceed 2.5 Earth radii. It was discovered in 2023 by the transit method, in which a planet passing in front of its star from our viewpoint causes a small dip in observed brightness; repeated dips help establish orbital periods.
TOI-2194 b has an orbital period of 15.3 days and a radius of 1.99 Earth radii, larger than Earth's radius.
