Dr. Georg Waltemath was an astronomer from Hamburg, best known for his 1898 claim of a second moon of Earth as well as a system of tiny moons.〔Observatoire de Lyon. ''Bulletin de l'Observatoire de Lyon''. Published in France, 1929, p. 55〕 It is widely held to be false. ==Second Moon== He is believed to have begun his search for one of the largest satellites which he claimed to exist based on the hypothesis that something was gravitationally affecting the Moon's orbit.〔Public Opinion: A Comprehensive Summary of the Press Throughout the World on All Important Current Topics, published by Public Opinion Co., 1898: "The Alleged Discovery of a Second Moon", p 369. (Book )〕 He gave detailed information into it which is given below: *Distance from earth: 1030000 km (640000 miles) *Diameter: 700 km (430 miles) *Orbital period: 119 days *Synodic period: 177 days He claimed that it was not normally visible with the naked eye but predicted it would be visible between 2 and 4 February 1898. 12 claims were made to have seen it at that time but were later proven fraudulent or mistaken by astronomers W. Winkler and Baron Ivo von Benko who had been monitoring the area at the time. Waltemath also claimed that the moon had been sighted previously by Adolphus Greely in Greenland on 24 October 1881 and by painter and personal friend, C. Waller in Munich on 16 February 1897. 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「Georg Waltemath」の詳細全文を読む スポンサード リンク
