HAT-P-15 and Its Jupiter-Like Planet
HAT-P-15 is a G5 star located 628 light-years away. A G-type dwarf like this is Sun-like in temperature class. The star is 6.8 billion years old, holds 1.01 solar masses, spans 1.08 solar radii, and has a temperature of 5570 K. Its reported radius estimate is larger than the Sun's, and its reported temperature is cooler than the Sun's. One planet orbits this host.
That planet is HAT-P-15 b, a Jupiter-like world discovered in 2010 by the transit method, in which a planet passes in front of its star from our viewpoint and causes a small dip in observed brightness. It completes an orbit in 10.9 days, with a radius of 11.9 Earth radii, larger than Earth's. Its mass of 617 Earth masses is also larger than Earth's, roughly 1.94 times Jupiter's mass. With a mean density of 2.03 g/cm³, it is 0.368 times Earth's.
