385446 Manwë (original) (raw)
(385446) Manwë ist ein transneptunisches Objekt im Kuipergürtel, das sich in einer 4:7-Bahnresonanz mit Neptun befindet. Manwë hat einen Mond names Thorondor, der etwa halb so groß wie Manwë ist. Daher wird dieses System als Doppelasteroidensystem bezeichnet.

(de) 385446 Manwë [ˈmanwɛ], or (385446) Manwë–Thorondor [θɔˈrɔndɔr], is a binary resonant Kuiper belt object in a 4:7 mean-motion resonance with Neptune. It was discovered on 25 August 2003, by American astronomer Marc Buie at Cerro Tololo Observatory in northern Chile. A study of Manwë's light curve in 2019 suggests that it may be a contact binary object. (en) (385446) Manwë est un objet transneptunien découvert le 25 août 2003 par Marc W. Buie au Cerro Tololo Inter-American Observatory. Sa désignation provisoire était 2003 QW111. (fr) (385446) Manwe ((385446) 2003 QW111) adalah sebuah objek trans-Neptunus. Seperti objek trans-Neptunus pada umumnya, benda ini mengorbit Matahari dari jarak yang lebih jauh dari planet Neptunus. Eksentrisitas orbit objek ini tercatat sebesar 0.115, sementara magnitudo mutlaknya adalah 6.5. (in) 385446 Manwë è un oggetto transnettuniano. Scoperto nel 2003, presenta un'orbita caratterizzata da un semiasse maggiore pari a 43,5777954 UA e da un'eccentricità di 0,1116274, inclinata di 2,66760° rispetto all'eclittica. Il suo diametro è valutato essere tra i 58 e i 92 km. Nel 2006 Keith Noll, Will Grundy, Harold Levison e Denise Stephens hanno determinato la natura binaria del corpo: il compagno, denominato 385446 I Thorondor, ha dimensioni, stimate tra i 35 e 53 km, pari a circa la metà del corpo principale, e percorre un'orbita caratterizzata da un semiasse maggiore di 6.674±41 km, un periodo di 110,176±0,018 giorni, un'eccentricità di 0,5632±0,0070 e un'inclinazione di 25,58±0,23°. Dal 15 aprile al 10 agosto 2014, quando 392728 Zdzisławłączny ricevette la denominazione ufficiale, è stato l'asteroide denominato con il più alto numero ordinale. Prima della sua denominazione, il primato era di 382238 Euphemus. L'asteroide è dedicato all'omonimo re di Arda e il satellite all'omonimo re delle Aquile, entrambi personaggi dell'universo immaginario dei romanzi di J. R. R. Tolkien. (it) (385446) Manwë – planetoida z Pasa Kuipera, krążąca w rezonansie orbitalnym 4:7 z Neptunem. (pl) 385446 Manwë é um objeto transnetuniano binário que está localizado no cinturão de Kuiper, uma região do Sistema Solar. Este corpo celeste está em uma ressonância orbital de 4:7 com o planeta Netuno. Ele possui uma magnitude absoluta de 6,5 e tem um diâmetro estimado com cerca de 151 km. O corpo secundário, Thorondor, é estimado para ter cerca de metade do tamanho do primário, 88 km contra 151 km de Manwë. A curva de luz tem uma grande variabilidade fotométrica, com a magnitude relativa dos dois objetos medidos variadamente 0,6-2,1, ao longo de uns poucos anos. (pt) (385446) Манвэ (англ.

Den har en banresonans med Neptunus av 4:7. Dess preliminära beteckning var 2003 QW111. Den fick senare namn efter Manwë, den mäktigaste bland Valar i J. R. R. Tolkiens fantasyvärld Midgård. Manwës nästa periheliepassage sker den 30 maj 2084. Asteroiden tros bestå huvudsakligen av is, eftersom dess densitet är lägre än vattnets. (sv) |
