Asteroid 1691, Oort, was discovered on September 9, 1956 by Karl Reinmuth and Ingrid Groeneveld at Heidelberg, Germany. It has a period of 5 years, 236 days.
It was named after Dutch astronomer Jan Hendrik Oort (1900-1992), a former director of the Leiden Observatory (from 1945 to 1970), a former president of the International Astronomical Union (from 1958 to 1961), and a well-known authority on stellar statistics and galactic structure. The Oort Cloud, the vast group of comets at the solar system's periphery, bears his name.
Jan Oort
The meaning of asteroid Oort seems to be: left over (Damien Foor); "ought" (to).
The glyph for Oort is mine.
