How many calcium atoms can fit between the Earth and the Moon? <br /><br />The distance from the surface of the Earth to the surface of the Moon is 384.467 km. <br />If along this distance place the calcium atoms along the line. <br />Given that the diameter of one calcium atom is 394 pm, then a chain of 975.8 * 10^15 calcium atoms will be obtained along this line. <br />This is a lot! <br />If all this amount is taken into account in mass, then this is less than one milligram of calcium. <br /><br />#calcium #earth #moon #Diametercalciumatom #Distancefromearthtomooninkilometers #Interestingfacts #Macrovsmicro #astronomy #atomic #facts #factsaboutspace
