Ed Tedesco



Research Areas:

  • Asteroid Collisional Evolution
  • Asteroid Physical Properties
  • Near-Earth Asteroids, especially those with orbits mostly, or entirely, interior to the Earth’s


Tedesco is interested in the origin and evolution, of the asteroid belt and in the physical properties of asteroid dynamical families and individual asteroids. He has been making and interpreting physical observations of asteroids since 1975 (Tedesco, 1976; Tedesco and Drummond, 1978) and was involved in the data reduction and publication of the IRAS Minor Planet Survey (Tedesco, 1992; Tedesco et al., 2002). He was also the first to model the efficiency of discovering NEOs using a space-based infrared sensor (Tedesco et al., 2000) and has made astrometric, lightcurve, multi-color photometry, phase curve, polarimetric, and radiometric observations using 0.4 to 8.2 meter ground-based telescopes and the IUE, IRAS, MSX, ISO, and Spitzer spacecraft (and was to have done the same on the WIRE mission). Recently he led an effort simulating the appearance on the sky of asteroids at various wavelengths (Tedesco, Cellino, and Zappalà, 2005). He has considerable experience in preparing data for, and submitting it to, the PDS-SBN, having contributed six datasets1 and portions of a seventh2. This experience will be helpful in establishing data archiving and reporting procedures with the Canadian Astronomical Data Centre (CADC) in support of the NESS project.


Tedesco is currently actively involved in collaborations with colleagues in Canada, Finland, France, Italy, Spain, the Ukraine, and the US on these and other asteroid research programs. He is PI of the US Science Team on the Canadian NEOSSat micro-satellite mission’s NESS project led by Alan Hildebrand (University of Calgary).
