(11778) Kingsford Smith is an asteroid of the main inner belt that 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 .
Mean solar distance ( major semi-axis ), eccentricity and inclination of the orbit plane of the asteroid correspond to the Flora family, a large group of asteroids named after (8) Flora . Asteroids of this family move in a 4: 9 orbital resonance with the planet Mars around the sun . The group is also called the Ariadne family, after the asteroid (43) Ariadne . According to the SMASS classification ( Small Main-Belt Asteroid Spectroscopic Survey ), a spectroscopic study by Gianluca Masi , Sergio Foglia and Richard P. Binzel at (11778) Kingsford Smith assumed a bright surface, so roughly speaking it could be be an S-asteroid .
(11778) Kingsford Smith was named on May 1, 2003 after the Australian aviation pioneer Charles Kingsford Smith .
