CHE SIGNIFICA DISTANCE MODULUS IN INGLESE
definizione di distance modulus nel dizionario inglese
La definizione del modulo di distanza nel dizionario è una misura della distanza, r, di un oggetto celeste troppo lontano per mostrare una parallasse misurabile. È dato da m-M = 5 log, dove m è la sua magnitudine apparente e M è la sua magnitudine assoluta.
