Properties
WASP-159 is a F-type subgiant with 1.41 times the Sun's mass, and double the Sun's radius. It radiates at 4.78 times the Sun's luminosity from its photosphere at an effective temperature of 6,120 K. WASP-159 is about 3 billion years old, and is metal-rich like many other planetary hosts.

Planetary system
In 2019, SuperWASP discovered an inflated "hot Jupiter" orbiting the star.
