Qatar-5 and Its Jupiter-Like Planet

Qatar-5 is a G-type main-sequence star located 1200 light-years away. It is a Sun-like dwarf with a spectral type of G2 V. The star has an age of 0.53 billion years, a mass of 1.13 solar masses, a radius of 1.08 solar radii, and a temperature of 5750 K. Its reported mass and radius estimates are both larger than the Sun's. One planet is known to orbit this host.

That planet is Qatar-5 b, a Jupiter-like world discovered in 2017 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 every 2.88 days. Its radius is 12.4 Earth radii, exceeding Earth's, and its mass is 1370 Earth masses, roughly 4.32 times Jupiter's mass and also larger than Earth's. Its mean density is 3.96 g/cm³, which is 0.719 times Earth's.
