TOI-1898: A Distant Star With a Single Giant Planet

TOI-1898 is a star 260 light-years away with one known planet in orbit around it. The star is estimated to be 3.1 billion years old, with a mass of 1.25 solar masses and a radius of 1.61 solar radii. Its temperature is 6240 K.

The planet, TOI-1898 b, was discovered in 2024 by the transit method, which detects the small dip in a star's brightness when a planet passes in front of it. TOI-1898 b is classified as Jupiter-like, meaning its radius exceeds four times Earth's. Its radius is 9.4 Earth radii and its mass is 129 Earth masses, both larger than Earth's corresponding values.

TOI-1898 b completes one orbit in 45.5 days. Its mean density is 0.857 g/cm³, which is 0.156 times Earth's. The host star's reported mass and radius are both larger than the Sun's, and its temperature is hotter than the Sun's.
