(12716) Delft is an asteroid of the main outer belt discovered on April 8, 1991 by the Belgian astronomer Eric Walter Elst at the La Silla Observatory of the European Southern Observatory in Chile ( IAU code 809).

The asteroid belongs to the Eos family , a group of asteroids which typically have large semiaxes from 2.95 to 3.1 AU , bounded inward by the Kirkwood gap of the 7: 3 resonance with Jupiter , and orbital inclinations between 8 ° and 12 °. The group is named after the asteroid (221) Eos . The family is believed to have emerged from a collision more than a billion years ago. The timeless (non- osculating ) orbital elements of (12716) Delft are almost identical to those of four smaller (assuming the absolute magnitude of 14.8, 16.1, 15.8 and 16.7 versus 13.7) asteroids : (132722) 2002 PV ₃ , (341683) 2007 VS ₁₀₇ , (375490) 2008 UR ₄₇ and 2013 BW ₂₉ .

(12716) Delft was named on August 19, 2008 after the South Dutch city of Delft .
