System

In 2000, an extrasolar planet was discovered orbiting the star.[1]

The star rotates at an inclination of 76+14
−42 degrees relative to Earth.[2] It has been assumed that the planet shares that inclination.[3] But several "hot Jupiters" are known to be oblique relative to the stellar axis.[4]
