Halobanor är möjliga vid L1, L2 eller L3 (banor visas inte i diagrammet).</figcaption></figure> <p>  En <b>halobana</b> är en periodisk, tredimensionell <a href="/wiki/Omloppsbana" title="Omloppsbana">omloppsbana</a> nära en av <a href="/wiki/Lagrangepunkt" title="Lagrangepunkt">Lagrange-punkterna</a> L<sub>1</sub>, L<sub>2</sub> eller L<sub>3</sub> i omloppsmekanismens <a href="/wiki/Trekropparsproblemet" title="Trekropparsproblemet">trekroppsproblem</a>. Även om en Lagrangepunkt bara är en punkt i rymden är dess säregna kännetecken att den kan kretsas runt av en Lissajous-bana eller av en halobana. Dessa kan ses som ett resultat av en växelverkan mellan gravitationskraften hos de två planetkropparna och <a href="/wiki/Corioliseffekten" title="Corioliseffekten">corioliseffekten</a> och <a href="/wiki/Centrifugalkraft" title="Centrifugalkraft">centrifugalkraften</a> på en rymdfarkost. Halobanor finns i alla system som består av tre kroppar, t.ex. ett satellitsystem som kretsar kring <a href="/wiki/Solen" title="Solen">solen</a> och <a href="/wiki/Jorden" title="Jorden">jorden</a> eller ett satellitsystem som kretsar kring jorden och <a href="/wiki/M%C3%A5nen" title="Månen">månen</a>. Kontinuerliga "familjer" av både norra och södra halobanor finns vid varje Lagrange-punkt.

En rymdfarkost i en sådan omloppsbana skulle vara i kontinuerlig direktkontakt med både jorden och månens baksida, medan en Lissajous-bana ibland skulle få rymdfarkosten att skymmas bakom månen sett från jorden. I slutändan användes ingen reläsatellit för Apollo eftersom alla landningar inom programmet var på framsidan av månen.<sup id="cite_ref-2" class="reference"><a href="#cite_note-2"><span class="cite-reference-link-bracket">[</span>2<span class="cite-reference-link-bracket">]</span></a></sup> </p><p>1973 upptäckte Farquhar och Ahmed Kamel att när en Lissajous-bana får tillräckligt stor amplitud skulle det finnas en motsvarande amplitud utanför planet som skulle ha samma period. Omloppsbanan upphörde då att vara en Lissajousbana och blev något som liknade en ellips. De använde analytiska uttryck för att representera dessa halobanor. 1984 visade Kathleen Howell att mer exakta banor kunde beräknas numeriskt. Hon fann dessutom att det för de flesta förhållandena mellan massorna av de två kropparna (som jorden och månen) fanns en rad stabila banor.<sup id="cite_ref-3" class="reference"><a href="#cite_note-3"><span class="cite-reference-link-bracket">[</span>3<span class="cite-reference-link-bracket">]</span></a></sup> </p><p>Det första uppdraget att i praktiken utnyttja en haloomloppsbana var <a href="/wiki/International_Cometary_Explorer" title="International Cometary Explorer">ISEE-3</a>, en gemensam satsning från <a href="/wiki/Europeiska_rymdorganisationen" title="Europeiska rymdorganisationen">ESA</a> och <a href="/wiki/NASA" title="NASA">NASA</a> som sköts upp 1978.
