Salve,
non sono sicuro che questa domanda abbia un senso, ma mi chiedevo:dopo quanto tempo, rispetto ad una coordinata temporale x (una data presa caso per fare un esempio, 10 Marzo 1662) i pianeti si ritrovano tutti contemporaneamente, rispetto al sole, nella stessa posizione che avevano in quella data?
Grazie.
Marco L.
Gentile Marco,
un modo per risolvere il problema è quello di calcolare il minimo comune multiplo tra i periodi di tutti i pianeti (per esempio espressi in anni o giorni, arrotondando all’intero più vicino).
Ad esempio:
tre pianeti che abbiano periodi di 6, 10 e 12 anni si ritroveranno nella stessa posizione dopo 60 anni, che è il m.c.m. tra i periodi.
