Measuring the size distribution of small NEOs with DECam [6.43 MB PDF]

Lori Allen

We used the Blanco + Dark Energy Camera to measure the size distribution of near-Earth asteroids from 1km diameter to 10m. I will describe the survey and present results. Preliminary results, published in Trilling et al. 2017, imply a factor of 10 fewer NEOs at the small end of the distribution than was previously predicted.
