Sul Washington Double Star Catalog vediamo come la Gamma Arietis (nome proprio Mesarthim) non sia una semplice doppia.&lt;br /&gt;
&lt;br /&gt;
Catalogata alla posizione 180 del catalogo di Struve, esiste anzitutto una componente STF180 AB (la coppia principale di cui ci occupiamo e i cui dati sono riportati nella tabella qui sopra).&lt;br /&gt;
Secondo Aitken, questa doppia fu osservata da Robert Hooke nel 1664 - si tratta quindi di una delle prime stelle doppie mai osservate.&lt;br /&gt;
&lt;br /&gt;
Esiste poi una coppia STF180 AC, la secondaria ha magnitudine 8.63, separazion 216.3&amp;quot; e angolo di posizione 82°.&lt;br /&gt;
&lt;br /&gt;
Esiste infine la doppia BU 512 CD (dove BU sta per Burnham, non già quello del Burnham' Celestial Handbook ma S.W. Burnham): la primaria di questa doppia è la componente C della STF180, la secondaria è una debole stella di magnitudine 13.6 a 1.6&amp;quot; di distanza, AP 24°.&lt;br /&gt;
&lt;br /&gt;

&amp;lt;div style=&amp;quot;text-align: center;&amp;quot;&amp;gt;''Mappa per l'individuazione della stella Gamma Arietis''&amp;lt;/div&amp;gt;&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
Mike Ropelewski, nel suo &amp;quot;A visual atlas of double stars&amp;quot;, scrive che &amp;quot;un piccolo telescopio a ingrandimento medio rivelerà due stelle bianco argento, di magnitudine 5, allineate N-S una rispetto all'altra contro uno sfondo di stelle abbastanza rarefatto&amp;quot;.&lt;br /&gt;
 &lt;br /&gt;
&lt;br /&gt;
Il punto vernale, noto anche come primo punto d'Ariete o punto gamma , è uno dei due punti equinoziali in cui l'equatore celeste interseca l'eclittica. Il nome viene dal simbolo Gamma che contraddistingue la costellazione dell'Ariete, e non già dalla stella Gamma Arietis.&lt;br /&gt;
Il punto d'Ariete corrispondeva all'equinozio di primavera di circa 2100 anni fa (nel periodo 2000 a.C. ÷ 100 a.C.): oggi a causa della precessione degli equinozi non è più così e in corrispondenza dell'equinozio di primavera il Sole si trova nella costellazione dei Pesci; a partire dal 2700 d.C. si troverà in quella dell'Acquario e così via fino al completamento dell'intero zodiaco.&lt;br /&gt;
