5899 Jedicke, provisional designation 1986 AH, is a

Carolyn Shoemaker at Palomar Observatory, and named after the members of the Canadian Jedicke family.[2][3]

Classification and orbit

Jedicke is a bright

Hungaria family, which form the innermost dense concentration of asteroids in the Solar System. It orbits the Sun in the inner main-belt at a distance of 1.7–2.2 AU once every 2 years and 8 months (978 days). Its orbit has an eccentricity of 0.12 and an inclination of 24° with respect to the ecliptic.[1]
It was first identified as 1978 EW3 at
Crimea–Nauchnij in 1978, extending the body's observation arc by 10 years prior to its official discovery observation at Palomar.[3]

Physical characteristics

Primary

According to the survey carried out by NASA's

albedo of 0.621.[7][8] The Collaborative Asteroid Lightcurve Link assumes an albedo of 0.30 – a compromise value between 0.4 and 0.2, corresponding to the Hungaria asteroids both as family and orbital group – and calculates a diameter of 3.51 kilometers with an absolute magnitude of 14.2.[4]

Between February 2010, and April 2016, astronomer

Moon

During Brian Warner's initial photometric observation in February 2010 – carried out in collaboration with mentor Alan W. Harris at the Space Science Institute in La Canada, California, Petr Pravec at Ondřejov Observatory in the Czech Republic, and Joseph T. Pollock at Appalachian State University, North Carolina – it was revealed that Jedicke is a synchronous binary system with a minor-planet moon orbiting it every 16.7 hours.[5]

Based on the observed mutual eclipse/occultation events, the satellite diameter measures at least 32% of that of Jedicke (i.e. a secondary-to-primary mean-diameter ratio of ≥ 0.32),

semi-major axis of 4.4 kilometers.[6]
