TOI-5181 A b: A Jupiter-Like World Around a Distant Star
TOI-5181 A is a star 1570 light-years away, and one known planet orbits it. The star is 4.1 billion years old and has a mass of 1.25 solar masses, a radius of 1.53 solar radii, and a temperature of 6060 K.
That planet, TOI-5181 A b, was discovered in 2025 by the transit method, which detects the small dip in a star's brightness when a planet passes in front of it. It is classified as Jupiter-like, meaning its radius exceeds 4 times Earth's radius. It has a radius of 13.3 Earth radii and a mass of 331 Earth masses, both larger than Earth's corresponding values. Its mean density is 0.765 g/cm³, 0.139 times Earth's. The planet completes an orbit every 3.89 days.
