宇宙メモ

・地球の直径 = 12,742km = 12,742,000m = 12,742,000,000mm
・月の直径 = 3,474km = 3,474,000m = 3,474,000,000mm
・太陽の直径 = 1,391,400km = 1,391,400,000m = 1,391,400,000,000mm
・地球と月の距離 = 384,400km = 384,400,000m = 384,400,000,000mm
・地球と太陽の距離 = 149,600,000km = 149,600,000,000m = 149,600,000,000,000mm

10億分の1スケールだと
・地球の直径 = 12.7mm = 1.27cm
・月の直径 = 3.5mm = 0.35cm
・太陽の直径 = 1,391.4mm = 139.1cm
・地球と月の距離 = 384.4mm = 38.44cm
・地球と太陽の距離 = 149,600mm = 14,960cm = 149.6m
