con la prima lettera greca α, o anche <b>RA</b> dalle iniziali della sua traduzione inglese <i>right ascension</i>) è un termine associato al <a href="/wiki/Sistema_di_coordinate_equatoriali" title="Sistema di coordinate equatoriali">sistema di coordinate equatoriali</a>. L'ascensione retta è analoga alla <a href="/wiki/Longitudine" title="Longitudine">longitudine</a>, ma proiettata sulla <a href="/wiki/Sfera_celeste" title="Sfera celeste">sfera celeste</a> anziché sulla superficie terrestre. Viene definita come <a href="/wiki/Distanza_angolare" title="Distanza angolare">distanza angolare</a> fra il meridiano fondamentale (il <a href="/wiki/Coluro" title="Coluro">coluro equinoziale</a>) e il meridiano passante per l'oggetto scelto, misurata lungo il parallelo passante per l'oggetto celeste. Lo zero corrisponde al <a href="/wiki/Punto_vernale" title="Punto vernale">primo punto d'Ariete</a> (punto dell'<a href="/wiki/Equinozio" title="Equinozio">equinozio</a> primaverile boreale). L'ascensione retta è misurata in <a href="/wiki/Ora" title="Ora">ore</a>, <a href="/wiki/Minuto" title="Minuto">minuti</a> e <a href="/wiki/Secondo" title="Secondo">secondi</a>, corrispondenti alla <a href="/wiki/Periodo_di_rotazione" title="Periodo di rotazione">rotazione terrestre</a>: 24 ore di ascensione retta sono un giro completo. Un'ora equivale a 15 gradi (da notare che l'ascensione retta usa il <a href="/wiki/Tempo_siderale" title="Tempo siderale">tempo siderale</a> e non quello civile).<sup id="cite_ref-1" class="reference"><a href="#cite_note-1"><span class="cite-bracket">[</span>1<span class="cite-bracket">]</span></a></sup> </p><p>L'ascensione retta può essere usata per trovare la posizione di una <a href="/wiki/Stella" title="Stella">stella</a> e per calcolare quanto tempo le occorrerà per trovarsi in un certo punto del cielo. Per esempio, se una stella con AR = 01<sup>h</sup> 30<sup>m</sup> 00<sup>s</sup> si trova su un dato meridiano, una stella con AR = 10<sup>h</sup> 00<sup>m</sup> 00<sup>s</sup> si troverà sullo stesso meridiano in 8 ore e 30 minuti <a href="/wiki/Tempo_siderale" title="Tempo siderale">siderali</a>. </p><p>A causa dei lenti movimenti della <a href="/wiki/Terra" title="Terra">Terra</a> (primo fra tutti la <a href="/wiki/Precessione_degli_equinozi" title="Precessione degli equinozi">precessione degli equinozi</a>), il sistema di coordinate su cui si basa l'ascensione retta cambia lentamente nel tempo ed è necessario specificare l'<a href="/wiki/Epoca_(astronomia)" title="Epoca (astronomia)">epoca</a> astronomica a cui ci si riferisce. </p> <div class="mw-heading mw-heading2"><h2 id="Note">Note</h2><span class="mw-editsection"><span class="mw-editsection-bracket">[</span><a href="/w/index.php?title=Ascensione_retta&veaction=edit&section=1" title="Modifica la sezione Note" class="mw-editsection-visualeditor"><span>modifica</span></a><span class="mw-editsection-divider"> | </span><a href="/w/index.php?title=Ascensione_retta&action=edit&section=1" title="Edit section's source code: Note"><span>modifica wikitesto</span></a><span class="mw-editsection-bracket">]</span></span></div> <div class="mw-references-wrap"><ol class="references"> <li id="cite_note-1"><a href="#cite_ref-1"><b>^</b></a> <span class="reference-text"><cite class="citation web" style="font-style:normal"> <a rel="nofollow" class="external text" href="http://www.treccani.it/enciclopedia/ascensione-retta/"><span style="font-style:italic;">ascensione retta</span></a>, su <span style="font-style:italic;">treccani.it</span>. <small>URL consultato il 3 marzo 2016</small>.</cite></span> </li> </ol></div> <div class="mw-heading mw-heading2"><h2 id="Voci_correlate">Voci correlate</h2><span class="mw-editsection"><span class="mw-editsection-bracket">[</span><a href="/w/index.php?title=Ascensione_retta&veaction=edit&section=2" title="Modifica la sezione Voci correlate" class="mw-editsection-visualeditor"><span>modifica</span></a><span class="mw-editsection-divider"> | </span><a href="/w/index.php?title=Ascensione_retta&action=edit&section=2" title="Edit section's source code: Voci correlate"><span>modifica wikitesto</span></a><span class="mw-editsection-bracket">]</span></span></div> <ul><li><a href="/wiki/Declinazione_(astronomia)" title="Declinazione (astronomia)">Declinazione (astronomia)</a></li> <li><a href="/wiki/Ascensione_retta_del_nodo_ascendente" title="Ascensione retta del nodo ascendente">Ascensione retta del nodo ascendente</a></li> <li><a href="/wiki/Coluro" title="Coluro">Coluro</a></li></ul> <div class="mw-heading mw-heading2"><h2 id="Collegamenti_esterni">Collegamenti esterni</h2><span class="mw-editsection"><span class="mw-editsection-bracket">[</span><a href="/w/index.php?title=Ascensione_retta&veaction=edit&section=3" title="Modifica la sezione Collegamenti esterni" class="mw-editsection-visualeditor"><span>modifica</span></a><span class="mw-editsection-divider"> | </span><a href="/w/index.php?title=Ascensione_retta&action=edit&section=3" title="Edit section's source code: Collegamenti esterni"><span>modifica wikitesto</span></a><span class="mw-editsection-bracket">]</span></span></div> <ul><li><cite class="citation web" style="font-style:normal"> <a rel="nofollow" class="external text" href="http://www.osservareilcielo.altervista.org/carte.html"><span style="font-style:italic;">Carte stellari, ascensione retta e declinazione</span></a>, su <span style="font-style:italic;">osservareilcielo.altervista.org</span>.</cite></li></ul> <style data-mw-deduplicate="TemplateStyles:r140554510">.mw-parser-output .CdA{border:1px solid #aaa;width:100%;margin:auto;font-size:90%;padding:2px}.mw-parser-output .CdA th{background-color:#f2f2f2;font-weight:bold;width:20%}@media screen{html.skin-theme-clientpref-night .mw-parser-output .CdA{border-color:#54595D}html.skin-theme-clientpref-night .mw-parser-output .CdA th{background-color:#202122}}@media screen and (prefers-color-scheme:dark){html.skin-theme-clientpref-os .mw-parser-output .CdA{border-color:#54595D}html.skin-theme-clientpref-os .mw-parser-output .CdA th{background-color:#202122}}</style><table class="CdA"><tbody><tr><th><a href="/wiki/Aiuto:Controllo_di_autorit%C3%A0" title="Aiuto:Controllo di autorità">Controllo di autorità</a></th><td><a href="/wiki/Gemeinsame_Normdatei" title="Gemeinsame Normdatei">GND</a> <span class="uid">(<span style="font-weight:bolder;
