Qatar-3 and Its Jupiter-like Planet
Qatar-3 is a G-type main-sequence star located 2400 light-years away. It is 0.31 billion years old, with a mass of 1.15 solar masses and a radius of 1.27 solar radii. Its temperature is 6010 K. The host star's reported mass and radius estimates are larger than the Sun's, and its reported temperature is hotter than the Sun's.
One planet orbits this star. Qatar-3 b is a Jupiter-like planet discovered by transit in 2017. It completes an orbit in 2.51 days. Its radius is 12.3 Earth radii, larger than Earth's, and its mass is 1370 Earth masses, also larger than Earth's and roughly 4.31 times Jupiter's mass. Its mean density is 4.07 g/cm³, 0.739 times Earth's.
