It is smaller and less luminous than our Sun , with a spectral class of K3V, which makes it an orange-red hued star. HR is relatively close to our system, with an estimated distance of This star is close to the limit of apparent magnitude that can still be seen by the unaided eye. The limit is considered to be magnitude 6 for most observers.
This star has a magnitude 9. As of March , the star is known to have at least 5 planets, two of them HD b and c known to be transiting, rocky Super-Earths. Coordinates : 23 h 13 m From Wikipedia, the free encyclopedia.
