TOI-5344: A Cool Star With a Close Jupiter-Like Planet
TOI-5344 is a single star located 451 light-years away. The star is 7.1 billion years old and has a mass of 0.59 solar masses and a radius of 0.563 solar radii, making it smaller than the Sun. Its temperature of 3770 K is cooler than the Sun's. One planet has been found orbiting this host.
That planet is TOI-5344 b, a Jupiter-like world discovered by transit in 2023. Transit observations detect the slight dimming caused when a planet crosses in front of its star. TOI-5344 b orbits once every 3.79 days, so its year is just 3.79 days long. Its radius of 10.6 Earth radii is larger than Earth's, and its mass of 131 Earth masses is also larger than Earth's. The planet's mean density is 0.605 g/cm³, 0.11 times Earth's.
