Sistema ticonico

Il sistema ticonico (o ticoniano) fu un modello del sistema solare proposto nel 1588 dall'astronomo danese Tycho Brahe, che creò nuova strumentazione astronomica e fece le osservazioni più accurate mai fatte prima dell'invenzione del telescopio.

Per quanto riguarda il moto relativo dei pianeti fra loro e rispetto al Sole il sistema ticonico è completamente equivalente al sistema eliocentrico.^[1] Esso, inoltre, corrispondeva alle osservazioni astronomiche meglio del sistema copernicano.^[2]

Col suo sistema Tycho ottenne i "benefici matematici" del sistema eliocentrico copernicano e contemporaneamente soddisfò le esigenze filosofiche e "fisiche", che avevano motivato il sistema geocentrico aristotelico-tolemaico.
