L'equatore celeste è un cerchio massimo proiettato sull'immaginaria sfera celeste, che può essere costruito ingrandendo l'equatore terrestre finché non interseca la sfera celeste. È inclinato di circa 23° 27' rispetto al piano dell'eclittica, riflettendo l'uguale inclinazione dell'asse di rotazione terrestre.
