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]

Orbit and classification

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]

Physical characteristics

Bohmia's spectral 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 

Diameter and albedo

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]

Rotation period

No rotational lightcurve of Bohmia has been obtained from photometric observations. The asteroid's rotation period, poles and shape remain unknown. [1] [8]

Naming

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 Planets by Paul Herget in 1955 ( H 107). [2]
