4179 Toutatis is a near-Earth asteroid with a chaotic, unpredictable rotation.

Where 4179 fits
Why 4179 is special
It tumbles rather than spinning about a fixed axis, so it has no fixed day length. Very few objects rotate this way, and it makes long-term prediction of its orientation impossible.

4 × 1,000 + 1 × 100 + 7 × 10 + 9 × 1 = 4,179. 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.

Related numbers & connections
Toutatis tumbles chaotically and Aten gives its name to asteroids orbiting mostly inside Earth's path. Both complicate prediction, one of orientation and one of detection.
View 2062 →Science
Toutatis tumbles chaotically rather than rotating about a stable axis, so it has no definable rotation period. Its orientation cannot be predicted far ahead even though its orbit can.
