Asteroid 13777, Cielobuio, was discovered on October 20, 1998 Oct. 20 by Marco Cavagna and Augusto Testa at Sormano, Como, Italy. It has a period of 5 years, 19 days.
It was named for an Italian non-profit organization called Cielobuio (Italian for "dark sky"), which combats light pollution.
Astrologically, asteroid Cielobuio seems to have to do with what dark skies might suggest. This was originally suggested by Francesco Schiavinotto.
The glyph for Cielobuio is mine.
