(11774) Jerne is an asteroid of the outer main belt , which was discovered on October 17, 1977 by the Dutch astronomer couple Cornelis Johannes van Houten and Ingrid van Houten-Groeneveld . The discovery took place during the 3rd Trojan survey, during which Tom Gehrels surveyed field plates recorded by the 120 cm Oschin Schmidt telescope of the Palomar observatory at the University of Leiden , 17 years after the start of the Palomar-Leiden- Surveys . Unconfirmed sightings of the asteroid had previously been made at the Palomar Mountain Observatory in September 1960 under the provisional designation 4192 PL as part of the first Palomar Leiden survey.

(11774) Jerne was named on May 1, 2003 after the Danish physician and immunologist Niels Kaj Jerne (1911–1994). Jerne received the Nobel Prize for Physiology or Medicine in 1984 together with Georges JF Köhler and César Milstein “for theories about the specific structure and control of the immune system and for the discovery of the principle of the production of monoclonal antibodies ”. The asteroid of the inner main belt (11775) Koehler was named after Georges JF Köhler on the same day, and the asteroid of the outer main belt (11776) Milstein was named after César Milstein on May 1, 2003 .
