&lt;br /&gt;
Castore (Struve 1110), è la stella Alfa della costellazione dei Gemelli.&lt;br /&gt;
 &lt;br /&gt;
E’ una stella doppia distante circa 51 anni luce ed è una tra le più belle stelle doppie osservabili anche con strumenti modesti.&lt;br /&gt;
Le due componenti, hanno un colore bianco/azzurro e orbitano una attorno all’altra in circa 410 anni e le ultime misurazioni (2010) danno 58° come angolo di posizione e una separazione di 4,7”.&lt;br /&gt;
&lt;br /&gt;
La prima osservazione di questa bella coppia è stata fatta nel 1718 da Bradley e Pound,  che ne intuirono il moto proprio.&lt;br /&gt;
&lt;br /&gt;
Già Herschel, misurando parecchie volte la posizione reciproca nel corso degli anni delle due stelle, si avvide del lento moto orbitale della secondaria attorno alla primaria.&lt;br /&gt;
&lt;br /&gt;
Per il Reverendo Webb, è “il più bel sistema doppio del nostro emisfero. Eccellente per piccoli telescopi.”  &lt;br /&gt;
&lt;br /&gt;
Camille Flammarion, la descrive come una “gemma del cielo” e ne parla come di un sistema triplo. &lt;br /&gt;
&lt;br /&gt;
In effetti, a circa 70”di distanza, vi è una stella rosso /arancio di nona magnitudine, che sembra avere lo stesso moto proprio di Castore e venne misurata per la prima volta nel 1823, dall’astronomo inglese James South.&lt;br /&gt;
&lt;br /&gt;
Si tratta della componente AC del sistema. Esiste anche una componente AD di magnitudine 10.1, situata a 185.2&amp;quot; e secondo un angolo di posizione di 222° (dati del 1998).&lt;br /&gt;
&lt;br /&gt;
Inoltre A e B sono entrambe doppie spettroscopiche di periodo rispettivamente 9.21 e 2.93 giorni: un sistema di grande complessità.&lt;br /&gt;
