TOI-1272 b: A Jupiter-Like World Around a Cool Dwarf
TOI-1272 is a K-type main-sequence dwarf 449 light-years away, with a spectral type of K2 V - K3 V. Its mass is 0.828 solar masses, its radius is 0.8 solar radii, and its temperature is 4990 K. The star is 7 billion years old. Its mass and radius are both smaller than the Sun's, and it is cooler than the Sun.
One known planet orbits this star. TOI-1272 b was discovered by transit in 2022. With a radius of 4.26 Earth radii, it is a Jupiter-like planet, exceeding four times Earth's radius. Its mass is 24.1 Earth masses and its mean density is 1.72 g/cm³, 0.312 times Earth's. Both its mass and radius are larger than Earth's.
TOI-1272 b completes an orbit in 3.32 days.
