'''WASP-159''' is a faint star located in the southern [[constellation]] [[Caelum]]. With an [[apparent magnitude]] of 12.84, a powerful telescope is needed to see the star. The star is located {{Convert|2380|ly|pc|abbr=off|lk=on}} based on [[parallax]], but is drifting away with a heliocentric [[radial velocity]] of +35.16&nbsp;km/s.
== Properties ==
WASP-159 is a [[F-type star|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 [[Kelvin|K]]. WASP-159 is about 3 [[billion years]] old, and is metal-rich like many other planetary hosts.
== Planetary system ==
In 2019, [[Wide Angle Search for Planets|SuperWASP]] discovered an inflated "hot Jupiter" orbiting the star.<ref name="Hellier2019" />
