TOI-7009 and Its Neptune-Like Planet
TOI-7009 is a star 601 light-years from Earth with one known planet. Its reported mass estimate is 0.583 solar masses and its reported radius estimate is 0.564 solar radii, both smaller than the Sun's. The star's reported temperature is 4080 K, cooler than the Sun's. An estimate is approximate.
The planet TOI-7009 b is Neptune-like, meaning its radius reaches up to 4 times Earth's. It was found by transit, in which a planet passes in front of its star from our viewpoint and causes a small dip in observed brightness; repeated dips help establish orbital periods. TOI-7009 b has an orbital period of 2.32 days and a radius of 3.71 Earth radii, larger than Earth's.
