(11757) Saltpeter 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 was named on March 6, 2004 after the Austro-Australian astrophysicist Edwin Salpeter (1924-2008), who as a professor at Cornell University together with Hans Bethe developed the Bethe-Salpeter equation for bound states in quantum field theory and who in 1964 helped Jakow Seldowitsch was the first to propose accretion disks around black holes as models for quasars and active galaxies.
