Njihovo leto \u2013 \u010das, ki ga potrebujejo za en obhod \u2013 se spreminja glede na njihovo oddaljenost od Sonca. Leto na Merkurju traja le 88 zemeljskih dni, zato bi nekdo, rojen tam, imel \u0161tirikrat ve\u010d rojstnih dni kot mi na Zemlji. Nasprotno pa leto na Plutonu ustreza 248 na\u0161im letom. Nekdo, rojen na Plutonu, ne bi nikoli praznoval rojstnega dne!<\/p>\n<\/div>\n<p>Venera in Merkur nimata naravnih satelitov, vsi ostali sedem planetov pa imajo lune, ki kro\u017eijo okoli njih. Doslej je bilo zabele\u017eenih skupno 138 lun. Ve\u010dina lun je zelo majhnih in jih je te\u017eko opaziti, celo z velikimi teleskopi. Trenutno je rekorder Jupiter z 63 znanimi sateliti.
