1194 Aletta
1194 Aletta, provisional designation 1931 JG, is a dark, carbonaceous asteroid from the outer region of the asteroid belt, about 55 kilometers in diameter. It was discovered on 13 May 1931, by English-born South-African astronomer Cyril Jackson at the Union Observatory in Johannesburg, South Africa. The C-type asteroid orbits the Sun at a distance of 2.6–3.2 AU once every 4 years and 12 months (1,816 days). Its orbit is tilted by 11 degrees to the plane of the ecliptic and shows an eccentricity of 0.09. Two concurring photometric light-curve analysis from the Leura/Kingsgrove Observatory and the Palomar Transient Factory Survey rendered a rotation period of 20.39 hours, with an alternative measurement from the Via Capote Observatory, that gave a slightly shorter period of 19.7 hours. According to the surveys carried out by the Infrared Astronomical Satellite IRAS, the Japanese Akari satellite, and the NEOWISE mission of the Wide-field Infrared Survey Explorer, the body has an albedo between 0.04 and 0.09, while the Collaborative Asteroid Lightcurve Link (CALL) derives a lower value of 0.03. The discoverer named the asteroid after his wife, Aletta Jackson.
