(9714) Piazzismyth Main-belt Asteroid
Discovered on 1 June 1975 by R. H. McNaught at Siding Spring.
Charles Piazzi Smyth (1819–1900) spent a decade in South Africa working on positional astronomy and geodesy, before taking up the post as the 2nd Astronomer Royal for Scotland. He pioneered astronomical site testing in Tenerife and other high altitudes and contributed to the development of spectroscopy, especially of the Sun.Naming citation (WGSBN Bull. 2, #1, 6), IAU / Minor Planet Center, via NASA/JPL
