If you had a scale model of the solar system would you be able to see the moon or sun with a 100 meter eye distance.(idk if i said that right please help)

Surely if you were 100m from the sun, it would be quite visible

if you were looking at the earth, not so much.
The distance is 150 million km
scale that to 100m, and the earth would be 1/(15*10^10) as big
the diameter of the earth is 12.37*10^9 m
so scale that (and check my math)
