HAT-P-44: A Distant Star With Two Known Planets

HAT-P-44 is a star 1130 light-years away with two known planets. The star is 7.5 billion years old, has 0.942 solar masses, 0.949 solar radii, and a temperature of 5300 K. Its mass estimate is smaller than the Sun's, and its temperature is cooler than the Sun's.

HAT-P-44 b is a Jupiter-like planet discovered by transit in 2014. It has 112 Earth masses, a radius of 13.9 Earth radii, and an orbital period of 4.3 days. Its radius estimate is larger than Earth's, its mass estimate is larger than Earth's, and its mean density is 0.228 g/cm³, 0.0415 times Earth's. Among the listed planets, it has the shortest year by reported estimates.

HAT-P-44 c was discovered by radial velocity in 2014. It has a minimum mass of 1270 Earth masses and an orbital period of 872 days. Its minimum mass is larger than Earth's and roughly 4 times Jupiter's mass. Among the listed planets, it has the longest year by reported estimates.
