TOI-1279 and Its Neptune-Like Planet
TOI-1279 is a star 349 light-years away with one known planet in its system. The host star is 4.2 billion years old, with a mass of 0.878 solar masses and a radius of 0.843 solar radii. Its temperature is 5460 K. The star's reported mass and radius estimates are smaller than the Sun's, and its reported temperature is cooler than the Sun's.
The planet TOI-1279 b was discovered by transit in 2024. A transit occurs when a planet passes in front of its star from our viewpoint, causing a small dip in observed brightness. TOI-1279 b is Neptune-like and orbits every 9.61 days. It has a radius of 2.66 Earth radii and a mass of 10.6 Earth masses, both larger than Earth's corresponding values. Its mean density is 3.1 g/cm³, 0.562 times Earth's.
