836 Jole
836 Jole ("prov. designation:" "or" ) is a bright background asteroid from the inner regions of the asteroid belt. It was discovered on 23 September 1916, by German astronomer Max Wolf at the Heidelberg Observatory in southwest Germany. The stony S-type asteroid has a rotation period of 9.6 hours and measures approximately in diameter. It was named after Iole, wife of Heracles from Greek mythology. Orbit and classification. Located in the orbital region of the Flora family, "Jole" is a non-family asteroid of the main belt's background population when applying the hierarchical clustering method to its  proper orbital elements. It orbits the Sun in the inner asteroid belt at a distance of 1.8–2.6 AU once every 3 years and 3 months (1,184 days; semi-major axis of 2.19 AU). Its orbit has an eccentricity of 0.18 and an inclination of 5° with respect to the ecliptic. The asteroid was first observed as A903 QA at Heidelberg Observatory on 24 August 1903, where the body's observation arc begins on the following night. Naming. Based on Lutz Schmadel's own research, this minor planet was named from Greek mythology, after Iole, daughter of King Eurytus of  Oechalia and wife by force of divine hero Heracles. The naming was not mentioned in "The Names of the Minor Planets" by Paul Herget in 1955. Physical characteristics. In the SDSS-based taxonomy, "Jole" is a common, stony S-type asteroid. Rotation period. In September 2010, a rotational lightcurve of "Jole" was obtained from photometric observations by Daniel Coley at the DanHenge Observatory at the Center for Solar System Studies. Lightcurve analysis gave a well-defined rotation period of hours with a brightness variation of magnitude (). Diameter and albedo. According to the survey carried out by the NEOWISE mission of  NASA's Wide-field Infrared Survey Explorer (WISE), "Jole" measures kilometers in diameter and its surface has an albedo of . Alternative mean-diameters published by the WISE team includes () and () with corresponding albedos of () and (). The "Collaborative Asteroid Lightcurve Link" assumes an albedo for a Florian asteroid of 0.24 and calculates a diameter of 6.21 kilometers based on an absolute magnitude of 13.2.
