1907 Rudneva
1907 Rudneva, provisional designation , is a stony background asteroid from the central regions of the asteroid belt, approximately 11 kilometers in diameter. It was discovered on 11 September 1972, by astronomer Nikolai Chernykh at the Crimean Astrophysical Observatory, Nauchnyj, on the Crimean peninsula. The asteroid was named after Soviet geodesist and war hero Yevgeniya Rudneva. Orbit and classification. "Rudneva" is a non-family asteroid from the main belt's background population. It orbits the Sun in the central asteroid belt at a distance of 2.4–2.7 AU once every 4 years and 1 month (1,484 days; semi-major axis  of 2.55 AU). Its orbit has an eccentricity of 0.04 and an inclination of 3° with respect to the ecliptic. The asteroid was first identified as at Johannesburg Observatory in August 1935. The body's observation arc begins with its identification as at Heidelberg Observatory in March 1938, almost 34 years prior to its official discovery observation at Nauchnyj. Physical characteristics. "Rudneva" is an assumed stony S-type asteroid. Rotation period. In April 2003, a fragmentary rotational lightcurve of "Rudneva" was obtained from photometric observations by French amateur astronomer René Roy. Lightcurve analysis gave a rotation period of 44  hours with a brightness amplitude of at least 0.1 magnitude (). As of 2017, no secure period of "Rudneva" has been obtained. Diameter and albedo. According to the survey carried out by the NEOWISE mission of NASA's Wide-field Infrared Survey Explorer, "Rudneva" measures between 10.977 and 11.848 kilometers in diameter and its surface has an albedo between 0.18 and 0.232. The "Collaborative Asteroid Lightcurve Link" assumes a standard albedo for stony asteroids of 0.20 and calculates a diameter of 11.83 kilometers based on an absolute magnitude of 12.0. Naming. This minor planet was named after Ukrainian-born Yevgeniya Rudneva  (1920–1944) a member of the "Astronomical–Geodetical Society of the U.S.S.R.", head of the solar department, and Hero of the Soviet Union. She voluntarily joined the army as a navigator in the all-female Night Bombers Aviation Regiment, known as the "Night Witches". She died in April 1944, while flying her 645th combat mission. The official was published by the Minor Planet Center on 20 February 1976 ().
