Comets and asteroids: searches and scares

Advances in Space Research, 2004
Abstract Concern that the Earth might be struck by a comet, with potentially devasting consequences, dates back some two centuries. With the growing appreciation in the twentieth century that asteroidal impacts are also a danger, search programs have been devised in the hope of discovering a specific hazard at least decades, and probably centuries or

Asteroid search operations with the space surveillance telescope

2016 IEEE Aerospace Conference, 2016
Over the past two years, the Lincoln Near Earth Asteroid Research (LINEAR) program, funded by the National Aeronautics and Space Administration (NASA), has transitioned to asteroid search operations using the new 3.5-meter wide-field-of-view Space Surveillance Telescope (SST) located at the Atom Site on White Sands Missile Range, N.M.

A new asteroid observation and search technique

Publications of the Astronomical Society of the Pacific, 1981
A prototype observatory was constructed near Socorro, New Mexico to search for and observe earth-approaching asteroids. Hardware modifications were made so that the discrimination of artificial satellites at an angular speed of 15 arcsec/sec can be used to observe minor planets at an angular speed of 0.01 arcsec/sec.

DISCOVERIES OF NEW ASTEROIDS UNDER THE INTERNATIONAL ASTEROID SEARCH COLLABOARATION

БЛИЗКИЯТ КОСМОС – ОБЩА ЦЕЛ
In the paper are presented results of remote asteroid observations made during monitoring campaigns that were part of the International Asteroid Search Collaboration Program for tracking and detection of asteroids. The methodology for detecting asteroids and the process of confirming the discoveries and naming the new objects by the International ...

Search for correlation between asteroid families and classes

Icarus, 1977
A correlation between membership in a dynamically defined asteroid family and membership in a given asteroid spectral class is sought. Examination of 10 families each with five or more classified members indicates a correlation for the 4 families whose existence is best established, and no correlation for the remaining 6 families.

Asteroid Thermal Radiation Inspired Search

The thermal radiation process of an asteroid exhibits complex dynamics involving energy absorption, storage, conduction, and re-release. Its dynamics are influenced by multiple factors, including rotation, surface roughness, thermal inertia, and asymmetric radiation.

Observation of Asteroids for Searching Extraterrestrial Artifacts

2013
Since the beginning of modern astronomy all evidence indicates that mankind’s place in the Universe is not central or exceptional. A major step was made into this direction recently when the availability of very high resolution spectrographs made it possible to detect giant and subgiant planets around Sun-like or smaller stars (Mayor 1995) and it was ...

Searching and Studying Binary Asteroids with AO Systems

2003
Our group has conducted adaptive optics observations of asteroids since 2001. Our main goal is the search and study of binary asteroids using several AO systems (Lick, Keck, VLT) and related technique such as Appulse (Berthier and Marchis, 2002) and Laser Guide Star observations (Marchis et al., AGU-EGS, 2003) to broaden the sample of asteroids ...
