TOI-5573 is a star 608 light-years away with an age of 9.7 billion years, a mass of 0.619 solar masses, a radius of 0.594 solar radii, and a temperature of 3790 K. Its reported mass and radius estimates are smaller than the Sun's, and its reported temperature is cooler than the Sun's. One planet is known to orbit this host.
That planet is TOI-5573 b, a Jupiter-like world discovered by transit in 2025. It has a mass of 112 Earth masses, a radius of 9.75 Earth radii, and an orbital period of 8.8 days. Its reported mass and radius estimates are larger than Earth's, and its mean density is 0.666 g/cm³, 0.121 times Earth's.
