(8868) Hjorter Main-belt Asteroid
Discovered on 1 March 1992 by UESAC at La Silla.
Olof Petrus Hjorter (1696-1750), Uppsala professor of astronomy in 1732-1737 and after 1746, independently discovered comet C/1743 X1 five days after Klinken-berg. With Celsius, he discovered the magnetic nature of aurorae. He donated his library to the Uppsala Observatory, and it is still the rarest part of that collection.Naming citation (19991123/MPCPages.arc), IAU / Minor Planet Center, via NASA/JPL
