IC 4665 is a cluster of about thirty stars that began to develop less than forty million years ago, lying about 1,400 light years from Earth in the constellation of Ophiuchus.
The cluster is just visible to the naked eye, as a faint point of light somewhat to the south of Ras Alhague.

 IC 4665   (Site not responding. Last check: 2007-10-15)
IC 4665 is a very conspicuous, coarse star cluster in the opera glas, but difficult to detect in the telescope so that neither Messier nor one of the Herschels found it.
IC 4665 has been discovered by the Swiss astronomer Philippe Loys de Cheseaux, according to the Webb Society Deep-Sky Observer's Handbook, Volume 3 (Open and Globular Star Clusters), p.
The bright star in the lower right (SW) of IC 4665 is Beta Ophiuchi, a red giant of spectral type K2 III and apparent visual magnitude 2.77 (not associated with the cluster).

In the north-eastern region of the constellation of Ophiuchus, near the famous 'Barnard's Star', is the large and bright open cluster, IC 4665.
An object that seems to receive very little attention, IC 4665 is a fine object for binoculars or a small telescope.
It is a scattered group of about 20 stars, most of which are white or bluish-white.

IC 4665 has been discovered by the Swiss astronomer Philippe Loys de Chéseaux.
Nevertheless, also this finding was not widespread enough so that it didn't find its way into the NGC or first IC catalog, but was only added to the second IC of 1908.

These two discoveries were announced along with the publication of Koehler's catalog in 1779 in the Astronomisches Jahrbuch for 1782.
Consequently, he continued to compile catalogs and atlasses, and in his 1782 "Vorstellung der Gestirne," publishes own independent rediscoveries of open clusters M48 (NGC 2548) and IC 4665 in Ophiuchus.
On January 6, 1779, Johann Elert Bode discovered the comet of that year (C/1779 A1, 1779 Bode).

 Cebalrai   (Site not responding. Last check: 2007-10-15)
From these data we find that the star has a very uncertain mass of about twice solar and that it is most likely now fusing helium into carbon in its deep core, having long ago given up the hydrogen fusion that powers more common ordinary stars like the Sun.
At first glance, Cebalrai is known more for its setting as anything else, as it makes a guidepost to the old, no-longer-recognized constellation "Poniatowski's Bull," a vee- shaped figure just to the east of the star, and to an attractive large star cluster (IC 4665) just to the northeast.
Closer physical examination, however, reveals Cebalrai to be oddly variable, not in brightness but in size.

During the Version War the wormhole contact to the IC 4665 cluster region in Ophuichus was destroyed, and the region was isolated until 9885 when the S¡iiws'nnii /STC bias drive ship Namor laid a wormhole to YTS 98754-34500, a G3/K5 binary system 15 LY from the cluster.
This system had been at one time colonised by the Interstellar Frontiers Group, but contact had been lost for 3300 years.
