1141 Bohmia, provisional designation 1930 AA, is a Florian asteroid from the inner regions of the asteroid belt, approximately 6 kilometers in diameter. It was discovered by German astronomer Max Wolf at the Heidelberg-Königstuhl State Observatory on 4 January 1930.[6] The asteroid was named after German philanthropist Katharina Bohm-Waltz.[2]

Bohmia is a member of the Flora family (402),[3] a giant asteroid family and the largest family of stony asteroids in the main-belt.[7]: 23 It orbits the Sun in the inner asteroid belt at a distance of 1.9–2.6 AU once every 3 years and 5 months (1,249 days; semi-major axis 2.27 AU). Its orbit has an eccentricity of 0.17 and an inclination of 4° with respect to the ecliptic.[1] The body's observation arc begins with its official discovery observation at Heidelberg in January 1930.[6]
Bohmia'sspectral type is unknown. However, its albedo is similar to that of the Flora family's parent body, 8 Flora, which is a stony S-type asteroid.[7]: 23
According to the survey carried out by the NEOWISE mission of NASA's Wide-field Infrared Survey Explorer, Bohmia measures 5.642 kilometers in diameter and its surface has an albedo of 0.251.[4][5]
No rotational lightcurveofBohmia has been obtained from photometric observations. The asteroid's rotation period, poles and shape remain unknown.[1][8]
This minor planet was named after Katharina Bohm-Waltz (died 1901), a German philanthropist who donated a 0.72-meter reflecting telescope (named Waltz reflector) to the discovering Heidelberg Observatory. The official naming citation was mentioned in The Names of the Minor PlanetsbyPaul Herget in 1955 (H 107).[2]
