(12136) Martinryle is an asteroid of the main belt that was discovered on September 24, 1960 by the Dutch astronomer couple Cornelis Johannes van Houten and Ingrid van Houten-Groeneveld . The discovery came about as part of the Palomar-Leiden survey , during which Tom Gehrels examined field plates recorded at the University of Leiden with the 120 cm Oschin Schmidt telescope of the Palomar observatory .
The asteroid belongs to the Eunomia family, a group named after (15) Eunomia , to which probably five percent of the asteroids in the main belt belong.
(12136) Martinryle was named on November 24, 2007 after the British radio astronomer Martin Ryle (1918–1984), who together with Antony Hewish received the Nobel Prize in Physics in 1974 for the development of a novel radio telescope system .
