No I think their statement was correct. I have nothing else to do and ratios interest me so read my mathmatical explanation if you wish.
Radius of the sun / Radius of the Earth = Size ratio
432,690 / 3,958.8 = 109.298272204
Rounded size ratio * Minimum part size = Corresponding ratio size of the sun
~109 * 0.001 = 0.109
Above is an attempted recreation of their screenshot but with my part sizes. Their part sizes were 0.001 and 0.05 and mine are posted above. Pretty close in my opinion.
Thanks for reading this waste of time reply, lol.
