Poyasnenie: Pochemu Oumuamua otklonyaetsya ot ozhidaemoi traektorii? V proshlom godu 1I/2017 U1 Oumuamua stal pervym izvestnym asteroidom iz mezhzvezdnogo prostranstva, proletevshim cherez nashu Solnechnuyu sistemu. Bol'she goda nazad etot kuvyrkayushiisya mezhzvezdnyi kusok skal'noi porody proletel dostatochno blizko ot Zemli. Budushuyu traektoriyu asteroida mozhno bylo legko predskazat' na osnovanii standartnoi teorii gravitacii, odnako okazalos', chto Oumuamua nemnogo otklonilsya ot etogo marshruta. Eta animaciya pokazyvaet, kak Oumuamua priblizhaetsya k nashemu Solncu i udalyaetsya ot nego, otmecheny ozhidaemaya i nablyudaemaya traektorii. Naibolee veroyatnaya gipoteza dlya ob'yasneniya otkloneniya – vybrosy gaza iz nagretogo Solncem asteroida, odnako vydvigayutsya i drugie predpolozheniya i prodolzhayutsya raboty po komp'yuternomu modelirovaniyu. Oumuamua nikogda ne vernetsya, no ozhidaetsya, chto sovremennye obzory neba smogut obnaruzhit' i otsledit' podobnye mezhzvezdnye asteroidy v techenie neskol'kih sleduyushih let.
