(5400) Anniewalker Main-belt Asteroid
Discovered on 4 February 1989 by Ueda, S., Kaneda, H. at Kushiro.
Anne (Annie) Walker (1863–1940) was the second female professional observational astronomer in Britain. From 1881 to 1903 she lived and worked at Cambridge Observatory as a computer and transit-circle observer. She was made redundant in 1903. The 1919 Appendix of revision observations for the 1897 AG Catalogue (Cambridge zone) was entirely her work.Naming citation (WGSBN Bull. 5, #4, 24), IAU / Minor Planet Center, via NASA/JPL
