HD 130322 is an 8th magnitude star in the constellation of Virgo. It is an orange dwarf, a type of star somewhat dimmer and cooler than our Sun. Spectral type of the star is K0V. It can only be seen with binoculars or telescope. Being almost exactly on the celestial equator the star is visible everywhere in the world except for the North Pole.
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]
