Planet Facts

Record the diameter of each of our nine planets (include Pluto), add them up, and then compare this number to the distance our moon is to the Earth. Use the link below for Planetary diameters and use the link above (Planet Facts) to find the distance from Earth to our moon by clicking on "Earth's Moon." If all the planets were lined up side by side would they be able to fit in between the distance from Earth to the moon? 
The distance to the moon is 384, 400 Km (238, 900 miles.)
