3628 Božněmcová, provisional designation Шаблон:Mp, is a rare-type asteroid from the middle region of the asteroid belt, approximately 7 kilometers in diameter. It was discovered on 25 November 1979, by Czech astronomer Zdeňka Vávrová at Kleť Observatory in the Czech Republic.[1] It is named for Czech writer Božena Němcová.[2]

Orbit and classification

Božněmcová orbits the Sun in the central main-belt at a distance of 1.8–3.3 AU once every 4.04 years (1,477 days). Its orbit has an eccentricity of 0.30 and an inclination of 7° with respect to the ecliptic.[3] It was first identified as Шаблон:Mp at Lowell Observatory in 1930, extending the body's observation arc by 49 years prior to its official discovery observation at Klet.[1]

Physical characteristics

In the SMASS taxonomy, Božněmcová is a bright O-type asteroid, a rare group with spectra that best fits those of the L6 and LL6 ordinary chondrite-type meteorites.[4]

Rotation period

In September 2007, a rotational lightcurve of Božněmcová was obtained from photometric observations by American astronomer Brian Warner at his Palmer Divide Observatory in Colorado. Lightcurve analysis gave a well-defined rotation period of 3.335410 hours with a low brightness amplitude of 0.09 magnitude (Шаблон:Small).[5]

Diameter and albedo

According to the surveys carried out by the Japanese Akari satellite and NASA's Wide-field Infrared Survey Explorer with its subsequent NEOWISE mission, Božněmcová measures between 5.40 and 8.14 kilometers in diameter, and its surface has an albedo between 0.256 and 0.359.[6][7][8][9] The Collaborative Asteroid Lightcurve Link assumes a standard albedo for stony asteroids of 0.20 and calculates a diameter of 8.18 kilometers at an absolute magnitude of 12.8, as the lower the albedo (reflectivity), the larger the body's diameter for an unchanged brightness.[10]

Naming

This minor planet was named in memory of Božena Němcová (1820–1862), a Czech writer, author of the novella The Grandmother (Шаблон:Lang-cs), the most frequently read book in Czech literature.[2] The official naming citation was published by the Minor Planet Center on 4 June 1993 (Шаблон:Small).[11]
