173 Ino is a large asteroid and the parent body of the Ino family, located in the central regions of the asteroid belt, approximately Script error: No such module "convert". in diameter. It was discovered on 1 August 1877, by French astronomer Alphonse Borrelly at Marseille Observatory in southern France, and named after the queen Ino from Greek mythology.[1][2] The dark Xk-type asteroid has a rotation period of 6.15 hours.[3]
Orbit and classification
Ino is the parent body and namesake of the Ino family (522Script error: No such module "Check for unknown parameters".),[4] an asteroid family in the intermediate main belt with nearly 500 known members.[5]Template:Rp The adjectival form of the asteroid name is "Inoan".
It orbits the Sun in the central main-belt at a distance of 2.2–3.3 AU once every 4 years and 6 months (1,659 days; semi-major axis of 2.74 AU). Its orbit has an eccentricity of 0.21 and an inclination of 14° with respect to the ecliptic.[6] The body's observation arc begins at Düsseldorf-Bilk Observatory in January 1879, five months after its official discovery observation at Marseilles.[1]
Physical characteristics
In the Tholen classification, Ino is a common carbonaceous C-type, while in the SMASS classification it is a Xk-subtype that transitions between the X-type and uncommon K-type asteroids.[6]
Multiple photometric studies of this asteroid were performed between 1978 and 2002. The combined data gave an irregular, asymmetrical light curve with a period of 6.163 ± 0.005 hours and a brightness variation of 0.10–0.15 in magnitude. The asteroid is rotating in a retrograde direction.[7]
