class=\"wp-block-paragraph\">In einem der Szenarien formte sich der Mond dadurch bereits rund fuenf Stunden nach dem Aufprall als kompakter Koerper. Waren die Kollisionspartner heisser und damit weicher, zerlegte der Einschlag Theia vollstaendig zu einer Truemmerscheibe, aus der der Mond erst nach und nach entstand. Entscheidend ist demnach der thermische Zustand der Ausgangskoerper &ndash; ein Faktor, den die Forschung lange fuer vernachlaessigbar hielt.<\/p>\n\n<h3 class=\"wp-block-heading\">Ein Modell, keine Beobachtung<\/h3>\n\n<p class=\"wp-block-paragraph\">Wichtig: Die Ergebnisse stammen aus Computersimulationen, nicht aus direkten Messungen. Warum Erde und Mond chemisch so aehnlich sind, bleibt weiter offen. Immerhin koennte der neue Ansatz kuenftig eingrenzen, wann genau sich der Mond gebildet hat.<\/p>\n\n<p class=\"wp-block-paragraph\"><em>Quelle: Die Studie von Denton, Asphaug u.&nbsp;a. erschien in &bdquo;The Astrophysical Journal Letters&ldquo; (DOI 10.3847\/2041-8213\/ae91e9).
