Description: Der Äquator ist eine gedachte Linie, die um die Erde verläuft, gleich weit vom Nord- und Südpol entfernt ist und senkrecht zur Rotationsachse der Erde steht. Der Äquator ist die Linie auf der Erdoberfläche, die am weitesten von der Rotationsachse entfernt ist. An den Polen schneidet sich diese Rotationsachse mit der Erdoberfläche. Im Koordinatensystem für Breiten- und Längengrade auf der Erdoberfläche hat der Äquator die geografische Breite 0°. Der Äquator unterteilt die Erde in eine nördliche und eine südliche Halbkugel. Orte auf der nördlichen Hemisphäre haben eine positive geografische Breite, Orte auf der südlichen Hemisphäre eine negative geografische Breite.
