Where 2244 fits
Why 2244 is special
The cluster is what cleared the hole at the nebula's centre, so the cavity is evidence of the stars rather than an absence of them.

In historical numeral systems
Egyptian
2 lotuses, 2 coils of rope, 4 hobbles, 4 strokes
2 × 1,000 + 2 × 100 + 4 × 10 + 4 × 1 = 2,244. The signs are simply repeated and added; where they sit on the line is a matter of layout, not value.
Babylonian
3 corner wedges + 7 vertical wedges (sixties place), 2 corner wedges + 4 vertical wedges (units place)
37 × 60 + 24 = 2244. Places are separated by a space on the tablet, with the higher place written first.
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.
