WASP-174 b: A Jupiter-like World in a Distant System
WASP-174 is an F6 V star located 1340 light-years away, with an age of 2.2 billion years. Its mass is 1.24 solar masses and its radius is 1.35 solar radii, both larger than the Sun's, and its temperature of 6400 K is hotter than the Sun's. One planet orbits this host.
That planet, WASP-174 b, was discovered in 2018 by the transit method, in which a planet passing in front of its star causes a small dip in observed brightness. It is a Jupiter-like planet, a size class that exceeds 4 times Earth's radius. Its radius is 16.1 Earth radii, larger than Earth's, and its mass is 105 Earth masses, also larger than Earth's. Its mean density is 0.138 g/cm³, 0.0251 times Earth's. WASP-174 b completes an orbit every 4.23 days.
