26471 Tracybecker           Discovered 2000 Jan. 8 by the Lincoln Laboratory Near-Earth Asteroid Research Team at Socorro.
Tracy Michelle Becker (b. 1986) determined the shapes of the components of asteroid (153591) 2001 SN 263 , the first triple-asteroid system discovered in the near-Earth population. She did this work as a student working at the Arecibo Observatory, earning a Ph.D. in 2016. Name suggested by M. Nolan and E. Howell.
