Where 7000 fits
Why 7000 is special
Its resemblance to the continent is a coincidence of which parts are obscured by foreground dust. The shape is defined by what cannot be seen rather than by the object itself.

7 × 1,000 = 7,000. The signs are simply repeated and added; where they sit on the line is a matter of layout, not value.
Systems that simply cannot reach this value are left out. Where a script needs a font most readers do not have, the reading is given instead of the glyphs — see number systems for each system in full.

The North America Nebula looks like the continent because a dust lane blocks light from the region corresponding to the Atlantic. The outline is drawn by obscuration rather than by structure.
