The decision of the Committee for Small Body Nomenclature to assign the name "Wikipedia" to the asteroid was published in the Minor Planet Circular of January 27, published online yesterday, page 82403. Wikimedia Ukraine board member Andriy Makukha proposed the name. It was submitted to the Committee by the head of the Andrushivka Astronomical Observatory in Ukraine, Yuri Ivashchenko.
The official dedication of the name says:
“Wikipedia is a free, copyleft, collaboratively edited online encyclopedia launched in 2001. In 11 years of its compilation it became one of the largest reference works and one of the most visited web-sites on the Internet. It is developed in more than 270 languages by enthusiasts from all over the world.”
