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 giant star (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. The brighter member of the pair, designated component A, is an aging giant star with a stellar classification of G8III. A giant star is a star with substantially larger radius and luminosity than a main-sequence (or dwarf) star of the same surface temperature.
