Where 60,190 fits
Why 60,190 is special
Neptune completed its first full orbit since discovery only in 2011, 165 years after it was found in 1846. No planet has been observed for a whole Neptunian year by more than one generation of astronomers.

6 × 10,000 + 1 × 100 + 9 × 10 = 60,190. 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.

Neptune's 165-year orbit is about twice Uranus's 84. Neptune has completed one circuit since its discovery in 1846; Uranus has managed close to three since 1781.

View 1846 →Science
Neptune was discovered in 1846 and completed its first orbit since then in 2011. A single Neptunian year spans about seven human generations of astronomy, which is why long-term observation of it is a relay rather than a career.
