- 3. DISTANCE MEASUREMENTMoon artificial eclipse by 2 cents coinCoin Observateur distance = 2280 mmMeasurements :Coin diameter = 19 mmMoon diameter Moon Observateur distance=Coin diameter Coin Observateur distanceMoon Observateur distance 2280 = Moon diameter 19Moon Observateur distance= Moon diameter120
- 4. FINAL CALCULATIONWe measured :Moon Observateur distance= Moon diameter120 Earth diameterMoon diameter=3,79Earth diameter =12551 kmSo : 12551Moon Observateur distance= 1203,79Moon Earth distance=397393 km
