 | At a distance of 5.94 light-years (1.82 parsecs), the fourth nearest star and the second nearest star system to the Sun, after the trinary system of Alpha Centauri. |
| It lies in the northernmost part of the constellation Ophiuchus, west of Cebelrai (Beta Ophiuchi), and was discovered in 1916 by Edward E. Barnard. |
| Being a red dwarf, it cannot be seen from Earth without the aid of a powerful telescope. |
| Zeta Ophiuchi - Wikipedia, the free encyclopedia (170 words) |
| Zeta Ophiuchi (ζ Oph / ζ Ophiuchi) is a star located in the constellation of Ophiuchus. |
| Although ζ Ophiuchi is a hot blue giant star it appears reddish due to interstellar dust that absorbs much of its light. |
| ζ Ophiuchi is roughly half way through the initial phase of its stellar evolution and will within the next few million years expand into a supergiant star before ending its life in a spectacular supernova. |
