Summary[edit]

Description
English: Motion of the Earth (blue, with cyan orbit) and the Moon (black, with grey orbit) around the Sun (the direction to which is indicated with yellow stripes of angular width 3 arcminutes).

Positions are shown with intervals of one day for thirteen days around first quarter. For clarity the sizes of Earth and Moon are exaggerated. Correct relative dimensions are shown below. A white cross indicates the position of the center-of-mass of the Earth-Moon system.

The orbit of the Moon around the Sun is at any time concave towards the Sun.
Deutsch: Bewegung der Erde (Blau, mit turkisfarbige Bahn) und des Mondes (Schwarz, mir grauer Bahn) rund um die Sonne (deren Richtung mit gelben Streifen mit enter Winkelöffnung von 3 Bogenminuten angezeigt ist).

Die Positionen sind mit Abständen von einem Tag für einen Zeitraum von 13 Tagen ums erste Viertel angegeben. Der Deutlichkeit halber sind die Grössen von Erde und Mond übertrieben. Korrekte Grössenverhältnisse sind unten gezeigt. Ein weisses Kreutz gibt den Schwerpunkt des Systems Erde-Mond an.

Die Bahn des Mondes ist stets zur Sonne gekrümmt.
Dansk: Bevægelsen af Jorden (blå, med cyan kurve) og Månen (sort, med grå kurve) omkring Solen (hvis retning er angivet med gule striber, der har en vinkelbredde på 3 bueminutter).

Positionerne vises med et døgns mellemrum igennem 13 døgn omkring første kvarter. For tydelighedens er størrelserne af Jorden og Månen overdrevet. Et hvis kors markerer beliggenheden af tyngdepunktet for Jord-Måne-systemet.

Månens bane omkring Solen krummer stedse ind mod Solen.
