(8644) Betulapendula is an asteroid of the inner main belt , which was discovered by the Belgian astronomer Eric Walter Elst on September 16, 1988 at the French Observatoire de Haute-Provence in the Alpes-de-Haute-Provence department ( IAU code 511). Unconfirmed sightings of the asteroid had already been made on May 17, 1980 (1980 KX) and October 23, 1981 (1981 UK 15 ) at the Crimean Observatory in Nautschnyj .
The mean diameter of the asteroid was calculated to be 4.391 km (± 0.151). The albedo of 0.303 (± 0.070) indicates a rather light surface.
(8644) Betulapendula was named on April 2, 1999 after the silver birch , whose scientific name is Betula pendula .
