8820 Anjandersen           Discovered 1985 Nov. 14 by P. Jensen at Brorfelde.
The research of Danish astrophysicist Anja C. Andersen (b. 1965) is an unusual combination of experimental, theoretical and observational work related to the properties and implications of dust particles. In 2005 she received the European Commission's Descartes Prize for outstanding excellence in science communication.
