1687 Glarona, provisional designation 1965 SC, is a stony asteroid from the outer region of the asteroid belt, approximately 34 kilometers in diameter. It was discovered by astronomer Paul Wild at Zimmerwald Observatory near Bern, Switzerland on 19 September 1965.[8]

The asteroid is a member of the Themis family, one of the larger groups in the outer main-belt. It orbits the Sun at a distance of 2.6–3.7 AU once every 5 years and 7 months (2,051 days). Its well-defined orbit shows an eccentricity of 0.18 and is tilted by 3 degrees to the plane of the ecliptic. It has a rotation period of 6.3 hours with an amplitude in brightness of 0.75 in magnitude.[a] The assumed S-type asteroid has an albedo of 0.06–0.16, according to observations made by the IRAS, Akari, WISE and NEOWISE surveys.[4][5][6][7] Moreover, based on its orbital elements, Glarona is also a Themistian asteroid, which are known to have low albedos, showing spectra of carbonaceous C-type bodies (also see Carbonaceous chondrites).[9]

The minor planet was named in honor of the discoverer's home valley, the canton and town of Glarus in Switzerland.[2] Paul Wild (1925–2014) was a prolific discoverer almost 100 asteroids, and is well-known for his discovery of comet Wild 2, which was visited by NASA's Stardust mission.
