“Space is big. You just won't believe how vastly, hugely, mind-bogglingly big it is. I mean, you may think it's a long way down the road to the chemist's, but that's just peanuts to space.” douglas adams
pencil eraser = 5 mm ~= 4 mm for Earth So, that might be half a yard (0.477 yard) assuming a little math since a ping pong ball diameter is 40 mm... what common object is about 1.43 feet?
Moon is 27% the size of Earth. https://nssdc.gsfc.nasa.gov/planetary/factsheet/moonfact.html So need a common object a bit over 1 mm in size for the moon
Maybe a map style push pin
In sum: 17ish inch box or beach ball 4-5 mm pencil eraser (end) 1 mm push pin (map type)
Then want to proportionally find the distance between each...
149597870700000 mm = 92955807 mi = Sun to Earth 384399861000 mm = 238855 mi = Earth to Moon Sun diam = 1391400000000 mm Earth diam = 12741981120 mm Moon diam = 3476200000 mm
