HAT-P-26: A Distant K-Type Star and Its Jupiter-Like Planet
HAT-P-26 is a star of spectral type K1 located 463 light-years away. It is smaller than the Sun in both mass and radius, at 0.816 solar masses and 0.788 solar radii, and cooler, with a temperature of 5080 K. Its age is 9 billion years. One planet orbits this host.
That planet, HAT-P-26 b, is a Jupiter-like world discovered by transit in 2010. It completes an orbit every 4.23 days. Its radius is 7.06 Earth radii, larger than Earth's, and its mass is 22.2 Earth masses, also larger than Earth's. Its mean density is 0.348 g/cm³, 0.0632 times Earth's.
