TOI-6109: A Very Young Star With Two Jupiter-Like Planets

TOI-6109 is a G3 star located 495 light-years away. It has a mass of 1.03 solar masses, a radius of 1.02 solar radii, and a temperature of 5660 K, cooler than the Sun. Its age is 0.075 billion years, placing it in the very young class. Two planets are known to orbit this star.

Both planets were discovered by transit in 2025 and are classified as Jupiter-like, with radii exceeding 4 times Earth's. TOI-6109 b orbits every 5.69 days and has a radius of 4.87 Earth radii, larger than Earth's. TOI-6109 c orbits every 8.54 days with a radius of 4.83 Earth radii, also larger than Earth's. Among the listed planets, TOI-6109 b has the shortest year and largest radius, while TOI-6109 c has the longest year and smallest radius.
