HAT-P-54 is a K7 star located 469 light-years away. Its mass is 0.645 solar masses and its radius is 0.617 solar radii, both smaller than the Sun's. The star's reported temperature is 4390 K, cooler than the Sun's, and its age is 3.9 billion years. One planet orbits this host.
That planet is HAT-P-54 b, a Jupiter-like world discovered in 2015 by the transit method. Its mass is 242 Earth masses and its radius is 10.6 Earth radii, both larger than Earth's. It completes an orbit in 3.8 days. Its mean density is 1.12 g/cm³, 0.204 times Earth's.
