1602 Indiana, provisional designation 1950 GF, is a stony asteroid from the inner regions of the asteroid belt, about 9 kilometers in diameter. It was discovered by the Indiana Asteroid Program at the U.S. Goethe Link Observatory near Brooklyn, Indiana, on 14 March 1950.〔 The asteroid is a member of the Flora family, a large group of stony S-type asteroids in the inner main-belt. It orbits the Sun at a distance of 2.0–2.5 AU once every 3 years and 4 months (1,229 days). Its orbit shows an eccentricity of 0.10 and is tilted by 4 degrees to the plane of the ecliptic. It has a rotation period of 2.6 hours〔〔 and a geometric albedo of about 0.25, based on the surveys carried out by the Akari and NEOWISE missions.〔〔 The minor planet was named for the U.S. state of Indiana and for Indiana University, the parent institution of the astronomy department and the observatory in which the planet was discovered.〔 Originally the discovery was credited to Beryl H. Potter (1901–1985), after whom the asteroid 1729 Beryl is named. She was research assistant at the Indiana University, who participated in the program of minor planet observations from 1949 to 1966. During this period, she analysed nearly 6,300 photographic plates, measuring the positions of minor planets and reporting lost asteroids to IAU's Minor Planet Circulars (MPCs) for publication. However, according to Frank K. Edmondson (1912–2008), chairman of the Astronomy Department of Indiana University ''(also see 1761 Edmondson)'', there were several assistants involved in blinking the photographic plates during the first years of the program. The discovery was therefore credited to Indiana University, instead.〔 == References == }} 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「1602 Indiana」の詳細全文を読む スポンサード リンク
