INEO—Imaging of near-Earth objects
Acta Astronautica, 1994Abstract INEO is a program of four explorer flyby missions for imaging near-Earth objects by means of small spin stabilized spacecrafts. A low-cost approach is achieved by using existing hardware and available scientific instrumentation. For the first mission the payload consists of the flight space model of the Halley multicolour camera and three ...

The SRT, near-earth objects and space debris
2006The 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.

Near-Earth Objects and the United Nations
2018This chapter presents the past, current and future efforts of the United Nations (UN) through its Office for Outer Space Affairs (UNOOSA) and the United Nations (UN) Committee on the Peaceful Uses of Outer Space (COPUOS) in the field of near-Earth objects and planetary defense.

In this paper we present visible and near-infrared spectroscopy of 7 peculiar NEOs. These objects have been observed within the SINEO (Spectral Investigation of Near-Earth Objects) survey, which have produced more then 100 spectra of NEOs. Among the objects presented here, five of them result to be spectrally peculiar, belonging to the rare V and R ...

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.Athanasia Toliou, Mikael Granvik

Near Earth Objects - a threat and an opportunity
Physics Education, 2003In the past decade the hazard posed to the Earth by Near Earth Objects (NEOs) has generated considerable scientific and public interest. A number of major films, television programmes and media reports have brought the issue to public attention. From an educational perspective an investigation into NEOs and the effects of impacts on the Earth forms a ...

A Near‐Earth Object Hazard Index
Annals of the New York Academy of Sciences, 1997ABSTRACT: With the advent of expanded near‐Earth object (NEO) surveys, the number of known close approaches to Earth will increase dramatically. For many of these objects, uncertainties in their preliminary orbits will result in calculations yielding nonzero probabilities of collision over the next century. An index system is proposed which places the

ExploreNEOs: The Warm Spitzer Near Earth Object survey
2011We 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 ...
