The SRT, near-earth objects and space debris

2006
The improvements, by means of radar observations, of the accuracy with which the orbits of near Earth asteroids and comets are determined are a key factor in order to be able to exclude future collisions of any of these bodies with the Earth. The SRT, once equipped with a suitable transmitter, can have an important role in this context.

ExploreNEOs: The Warm Spitzer Near Earth Object survey

2011
We are carrying out the ExploreNEOs project in which we observe more than 600 near Earth Objects (NEOs) at 3.6 and 4.5 microns with Warm Spitzer. For each NEO we derive diameter and albedo. We present our results to date, which include studies of individual objects, results for our entire observed sample, and, by extrapolation, results for the entire ...

Spitzer observations of Near Earth Objects

Bulletin of the American Astronomical Society, 2017
The Spitzer Space Telescope has proven to be a powerful tool to measure the diameters and albedos of Near Earth Objects. We have completed two major Spitzer NEO surveys (ExploreNEOs and NEOSurvey) and are in the middle of a culiminating third survey (NEOLegacy), with a total target list across all three programs of 2175 previously known NEOs. We report

Dynamical evolution of near-Earth objects

An apparent discrepancy between the number of observed near-Earth objects (NEOs) with small perihelion distances (q) and the number of objects that models predict, has led to the conclusion that asteroids get destroyed at non-trivial distances from the Sun.
