Tandis que la longitude sur la Terre est mesurée vers l'est ou vers l'ouest, l'ascension droite est toujours mesurée dans le <a href="/wiki/Sens_direct" class="mw-redirect" title="Sens direct">sens direct</a>, c'est-à-dire en sens croissant vers l'est. </p><p>De même que l'intersection entre le <a href="/wiki/M%C3%A9ridien_de_Greenwich" title="Méridien de Greenwich">méridien de Greenwich</a> et l'équateur sert de point d'origine pour la longitude terrestre, il existe un point d'origine pour l'ascension droite. Ce point, appelé <i><a href="/wiki/Point_vernal" title="Point vernal">point vernal</a></i> et noté <i>g</i> ou <i><a href="/wiki/%CE%93" class="mw-redirect" title="Γ">γ</a></i>, est un des deux points où l'<a href="/wiki/%C3%89quateur_c%C3%A9leste" title="Équateur céleste">équateur céleste</a> et l'<a href="/wiki/%C3%89cliptique" title="Écliptique">écliptique</a> se croisent et le cercle horaire passant par ce point est le cercle horaire de référence (ce cercle, ainsi que celui qui partage son diamètre ou axe Nord-Sud et décalé de 90°, portent le nom particulier de <a href="/wiki/Colure" title="Colure">colures</a>, colure des équinoxes (ou équinoxial) et colure des solstices (ou solsticial)). Le passage du <a href="/wiki/Soleil" title="Soleil">soleil</a> par ces deux points de croisement correspond aux équinoxes. Le <a href="/wiki/Point_vernal" title="Point vernal">point vernal</a> <i><a href="/wiki/%CE%93" class="mw-redirect" title="Γ">γ</a></i> correspond à la position du soleil lors de l'équinoxe de mars (début du printemps dans l'hémisphère nord, de l'automne dans l'hémisphère sud). </p><p>L'ascension droite se mesure toujours sous la forme d'un <i>angle</i> exprimé en <i>heures</i> (<sup>h</sup>), <i>minutes</i> (<sup>m</sup>), <i>secondes</i> (<sup>s</sup>), une heure étant équivalente à <span title="0,261 799 rad" style="cursor:help">15</span> <abbr class="abbr" title="degrés"><a href="/wiki/Degr%C3%A9_(angle)" title="Degré (angle)">degrés</a></abbr>. L'ascension droite varie donc de minuit à minuit. </p><p>L'ascension droite permet ainsi de déterminer facilement combien de temps (en <a href="/wiki/Temps_sid%C3%A9ral" title="Temps sidéral">temps sidéral</a>) il faudra à un astre pour atteindre un certain point dans le ciel. Par exemple, si une <a href="/wiki/%C3%89toile" title="Étoile">étoile</a> d'ascension droite 01:30:00 est au <a href="/wiki/M%C3%A9ridien_(astronomie)" class="mw-redirect" title="Méridien (astronomie)">méridien</a>, il faudra <span class="nowrap">18 <abbr class="abbr" title="heures">h</abbr> 30</span> à une autre étoile d'ascension droite 20:00:00 pour être au méridien (20 heures - <span class="nowrap">1 <abbr class="abbr" title="heure">h</abbr> 30</span>). </p><p>L'ascension droite n'est pas le seul angle qui ait été utilisé pour repérer la position des astres.

Cette dernière unité est assez peu utilisée. </p><p>Les minutes ou les secondes d'ascension droite sont ainsi distinctes des <a href="/wiki/Sous-unit%C3%A9s_du_degr%C3%A9" title="Sous-unités du degré">minutes ou secondes d'un arc</a>. Les heures, minutes et secondes d'ascension droite ne sont employées que dans le cas de la longitude céleste. Les degrés, minutes et secondes d'arc sont utilisés pour mesurer un angle quelconque. En règle générale, l'évocation de secondes (respectivement de minutes) quand on parle d'angles renvoie aux secondes d'arc (respectivement aux minutes d'arc), sauf précision contraire. </p> <div class="mw-heading mw-heading2"><h2 id="Voir_aussi">Voir aussi</h2><span class="mw-editsection"><span class="mw-editsection-bracket">[</span><a href="/w/index.php?title=Ascension_droite&veaction=edit&section=2" title="Modifier la section : Voir aussi" class="mw-editsection-visualeditor"><span>modifier</span></a><span class="mw-editsection-divider"> | </span><a href="/w/index.php?title=Ascension_droite&action=edit&section=2" title="Modifier le code source de la section : Voir aussi"><span>modifier le code</span></a><span class="mw-editsection-bracket">]</span></span></div> <ul><li><a href="/wiki/D%C3%A9clinaison_(astronomie)" title="Déclinaison (astronomie)">Déclinaison (astronomie)</a></li> <li><a href="/wiki/Longitude" title="Longitude">Longitude</a></li> <li><a href="/wiki/M%C3%A9ridien" title="Méridien">Méridien</a></li></ul> <ul id="bandeau-portail" class="bandeau-portail"><li><span class="bandeau-portail-element"><span class="bandeau-portail-icone"><span class="noviewer skin-invert-image" typeof="mw:File"><a href="/wiki/Portail:Astronomie" title="Portail de l’astronomie"><img alt="icône décorative" src="//upload.wikimedia.org/wikipedia/commons/thumb/2/27/Noun_Astronomy_Icon2.svg/25px-Noun_Astronomy_Icon2.svg.png" decoding="async" width="25" height="24" class="mw-file-element" srcset="//upload.wikimedia.org/wikipedia/commons/thumb/2/27/Noun_Astronomy_Icon2.svg/37px-Noun_Astronomy_Icon2.svg.png 1.5x, //upload.wikimedia.org/wikipedia/commons/thumb/2/27/Noun_Astronomy_Icon2.svg/50px-Noun_Astronomy_Icon2.svg.png 2x" data-file-width="755" data-file-height="730" /></a></span></span> <span class="bandeau-portail-texte"><a href="/wiki/Portail:Astronomie" title="Portail:Astronomie">Portail de l’astronomie</a></span> </span></li> </ul>    </div><noscript><img src="https://login.wikimedia.org/wiki/Special:CentralAutoLogin/start?type=1x1" alt="" width="1" height="1" style="border: none; position: absolute;"></noscript> <div class="printfooter" data-nosnippet="">Ce document provient de « <a dir="ltr" href="https://fr.wikipedia.org/w/index.php?title=Ascension_droite&oldid=214541565">https://fr.wikipedia.org/w/index.php?title=Ascension_droite&oldid=214541565</a> ».</div></div> <div id="catlinks" class="catlinks" data-mw="interface"><div id="mw-normal-catlinks" class="mw-normal-catlinks"><a href="/wiki/Cat%C3%A9gorie:Accueil" title="Catégorie:Accueil">Catégories</a> : <ul><li><a href="/wiki/Cat%C3%A9gorie:Angle" title="Catégorie:Angle">Angle</a></li><li><a href="/wiki/Cat%C3%A9gorie:Syst%C3%A8me_de_coordonn%C3%A9es_c%C3%A9lestes" title="Catégorie:Système de coordonnées célestes">Système de coordonnées célestes</a></li><li><a href="/wiki/Cat%C3%A9gorie:Unit%C3%A9_d%27astronomie" title="Catégorie:Unité d'astronomie">Unité d'astronomie</a></li></ul></div><div id="mw-hidden-catlinks" class="mw-hidden-catlinks mw-hidden-cats-hidden">Catégories cachées : <ul><li><a href="/wiki/Cat%C3%A9gorie:Portail:Astronomie/Articles_li%C3%A9s" title="Catégorie:Portail:Astronomie/Articles liés">Portail:Astronomie/Articles liés</a></li><li><a href="/wiki/Cat%C3%A9gorie:Portail:Sciences_de_la_Terre_et_de_l%27Univers/Articles_li%C3%A9s" title="Catégorie:Portail:Sciences de la Terre et de l'Univers/Articles liés">Portail:Sciences de la Terre et de l'Univers/Articles liés</a></li><li><a href="/wiki/Cat%C3%A9gorie:Portail:Sciences/Articles_li%C3%A9s" title="Catégorie:Portail:Sciences/Articles liés">Portail:Sciences/Articles liés</a></li></ul></div></div> </div> </main> </div> <div class="mw-footer-container"> <footer id="footer" class="mw-footer" > <ul id="footer-info"> <li id="footer-info-lastmod"> La dernière modification de cette page a été faite le 24 avril 2024 à 17:18.</li> <li id="footer-info-copyright"><span style="white-space: normal"><a href="/wiki/Wikip%C3%A9dia:Citation_et_r%C3%A9utilisation_du_contenu_de_Wikip%C3%A9dia" title="Wikipédia:Citation et réutilisation du contenu de Wikipédia">Droit d'auteur</a> : les textes sont disponibles sous <a rel="nofollow" class="external text" href="https://creativecommons.org/licenses/by-sa/4.0/deed.fr">licence Creative Commons attribution, partage dans les mêmes conditions</a> ; d’autres conditions peuvent s’appliquer.
