Asteroid 2471, Ultrajectum, was discovered on September 24, 1960 by the Palomar-Leiden Survey (Ingrid van Houten-Groeneveld, Tom Gehrels, and Cornelis Johannes [CJ]van Houten) at Palomar Observatory near Pauma Valley, California. It has a period of 5 years, 71 days.
It was named for the University Observatory at Utrecht (Ultrajectum in Latin), Netherlands. Utrecht was founded as the Roman fort of Trajectum (Latin for river crossing), which was dutchified to Trecht; the "U" was added from the Old Dutch "uut" (downriver) to differentiate Utrecht (Downriver Crossing) from another Dutch city named Maastricht (Crossing at the Meuse [River]). Utrecht was rendered into Medieval Latin as Ultrajectum.
The meaning of asteroid Ultrajectum seems to be: feeling alienated, excluded or ostracized; reclusive, detached.
