Where 4495 fits
Why 4495 is special
Sunlight there is about a thousandth of Earth's, yet Neptune has the fastest winds in the solar system at over 2,000 km/h. Where that energy comes from, with so little sunlight, is not fully explained.

4 × 1,000 + 4 × 100 + 9 × 10 + 5 × 1 = 4,495. 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.
