If 'halfway' is on the logarithmic scale (cant be on linear, it would be just half of the earth;) ) it rather a small pebel. ~4cm (taking the diameter of the carbon atom) https://www.wolframalpha.com/input?i=sqrt%28diameter+of+earth+*+diameter+of+carbon+atom%29
If we take diameter of only the nucleus, we are closer, 0.24mm https://www.wolframalpha.com/input?i=sqrt%28diameter+of+earth+*+diameter+of+carbon+atom+nucleus%29
This already can be qualified as dust, on the bigger part of the scale. But the picture is wrong, we have to take the size of only the nucleus, not the whole atom.
