Infrared Lightcurves of Near Earth Objects [PDF]

open access: yesThe Astrophysical Journal Supplement Series, 2018
We present lightcurves and derive periods and amplitudes for a subset of 38 near earth objects (NEOs) observed at 4.5 microns with the IRAC camera on the the Spitzer Space Telescope, many of them having no previously reported rotation periods.

NEOWISE Observations of Near-Earth Objects: Preliminary Results [PDF]

open access: yesThe Astrophysical Journal, 2011
With the NEOWISE portion of the \emph{Wide-field Infrared Survey Explorer} (WISE) project, we have carried out a highly uniform survey of the near-Earth object (NEO) population at thermal infrared wavelengths ranging from 3 to 22 $\mu$m, allowing us to ...

Search for design solutions to prevent the Kessler effect [PDF]

open access: yesE3S Web of Conferences, 2023
The article deals with the problems of near-earth space associated with the formation of objects called "space debris". The main sources of the appearance of "space debris" in near-earth orbits are highlighted.

NEOMOD: A New Orbital Distribution Model for Near-Earth Objects

open access: yesThe Astronomical Journal, 2023
Near-Earth Objects (NEOs) are a transient population of small bodies with orbits near or in the terrestrial planet region. They represent a mid-stage in the dynamical cycle of asteroids and comets, which starts with their removal from the respective ...

Unconfirmed Near-Earth Objects [PDF]

open access: yesThe Astronomical Journal, 2018
Abstract We studied the Near-Earth Asteroid (NEA) candidates posted on the Minor Planet Center’s Near-Earth Object Confirmation Page (NEOCP) between years 2013 and 2016. Out of more than 17000 NEA candidates, while the majority became either new discoveries or were associated with previously known objects, about 11% were unable to be ...

Optical Spectropolarimetry of Binary Asteroid Didymos–Dimorphos before and after the DART Impact

open access: yesThe Astrophysical Journal Letters, 2023
We have monitored the Didymos–Dimorphos binary asteroid in spectropolarimetric mode in the optical range before and after the DART impact. The ultimate goal was to obtain constraints on the characteristics of the ejected dust for modeling purposes ...

Validation of the Survey Simulator Tool for the NEO Surveyor Mission Using NEOWISE Data

open access: yesThe Planetary Science Journal, 2023
The Near-Earth Object Surveyor (NEO Surveyor) mission has a requirement to find two-thirds of the potentially hazardous asteroids larger than 140 m in size. In order to determine the mission’s expected progress toward this goal during design and testing,

Geoinformation modeling of near-Earth space: current tasks and future prospects [PDF]

open access: yesE3S Web of Conferences, 2021
The history of space exploration and current near-Earth space objects population are described in this paper. Moreover, the necessity of GIS technologies application to solve space industry tasks and the development of corresponding GIS are explained ...

Physical Characterization of Warm Spitzer-observed Near-Earth Objects [PDF]

open access: yes, 2012
Near-infrared spectroscopy of Near-Earth Objects (NEOs) connects diagnostic spectral features to specific surface mineralogies. The combination of spectroscopy with albedos and diameters derived from thermal infrared observations can increase the ...
