Where 7635 fits
Why 7635 is special
The bubble is blown by the stellar wind of a single massive star, which is off-centre because the surrounding gas is not uniform.

7 × 1,000 + 6 × 100 + 3 × 10 + 5 × 1 = 7,635. 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.
