A Search for Young Asteroid Pairs with Close Orbits

Solar System Research, 2020
We analyzed the dynamic evolution of a number of young asteroid pairs in close orbits in order to constrain their ages. Several methods of pair selection and estimation of their age are used: analysis of convergence of orbital elements; estimation of the Kholshevnikov metrics in the space of Keplerian orbital elements; estimation of relative distances ...

Search for solar wind–asteroid interactions at Eros

Advances in Space Research, 2004
The solar wind interaction with the asteroid 433 Eros is investigated using magnetometer data from the NEAR-Shoemaker spacecraft. From February 2000 to February 2001 NEAR-Shoemaker orbited Eros in nearly circular orbits having radii of 200, 100, 50 and 35 km.

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.

SST asteroid search performance 2014–2017

2018 IEEE Aerospace Conference, 2018
From 2014 to 2017, the Lincoln Near-Earth Asteroid Research (LINEAR) program performed wide-area asteroid search using the 3.5-m Space Surveillance Telescope (SST) located on Atom Peak at White Sands Missile Range, N.M. The SST was developed by MIT Lincoln Laboratory (MIT/LL) for the Defense Advanced Research Projects Agency (DARPA) to advance the ...

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.

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 ...

Asteroid Families: Search of a 12,487-Asteroid Sample Using Two Different Clustering Techniques

Icarus, 1995
A sample of over 12,487 asteroid proper element triplets, computed by A. Milani and Z. Kneževic (1994, Icarus 107, 219-254), has been searched for statistically significant and robust families by both the hierarchical clustering (HCM) and the wavelet analysis (WAM) automated techniques.

The Asteroid-Comet Continuum: In Search of Lost Primitivity

Elements, 2011
Recent results from the Stardust comet sample-return mission have confirmed the idea that there is a continuum between primitive small bodies in the outer main asteroid belt and comets. Indeed, the mineralogy as well as the chemical and oxygen isotope compositions of the dust from comet Wild 2 are very similar to those of carbonaceous chondrites, a ...

Some Results of the Faint Asteroid Search in Tautenburg

1988
In the last 20 years the whole world has witnessed an unexpected boom in minor planet astronomy. This was mainly due to the applica­tion of ever more sophisticated computers in calculating astrome­trio positions, orbital elements and ephemerides in the shortest possible time and storing a vast number of asteroid data.

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.
