Claim: Omicron Ophiuchi is a co moving star visible to the naked eye as a dim point of light, with the two components having apparent visual magnitudes of 5.14 and 6.59, with the brighter of the two being a yellow dawrf (a star with substantially larger radius and luminosity than a main-sequence (or dwarf) star of the same surface temperature) with a stellar classification of G8III.
Evidence: The co-moving pair are visible to the naked eye as a dim point of light, with the two components having apparent visual magnitudes of 5.14 and 6.59. A giant star is a star with substantially larger radius and luminosity than a main-sequence (or dwarf) star of the same surface temperature. The brighter member of the pair, designated component A, is an aging giant star with a stellar classification of G8III.
