(11776) Milstein is an asteroid of the outer main belt , which was discovered on October 16, 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 .
The orbit inclination of (11776) Milstein is small with rounded up 0.45 °, it is more similar to the plane of the earth's orbit around the sun than the orbit of the other seven planets .
The asteroid belongs to the Themis family, a group of asteroids named after (24) Themis . The timeless (non- osculating ) orbital elements of (11776) Milstein are almost identical to those of the smaller, if one assumes the absolute brightness of 15.2 compared to 13.7, asteroids (133839) 2003 YH 48 .
The asteroid was named on May 1, 2003 after the Argentine microbiologist César Milstein (1927–2002). In 1984 Milstein received the Nobel Prize for Physiology or Medicine together with Niels Kaj Jerne and Georges JF Köhler "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 outer main belt (11774) Jerne was named after Niels Kaj Jerne on the same day, and the asteroid of the inner main belt (11775) Koehler was named after Georges JF Köhler on May 1, 2003 .
