The Near-Earth Object Surveyor Mission [PDF]

open access: greenThe Planetary Science Journal, 2023
The Near-Earth Object (NEO) Surveyor mission is a NASA Observatory designed to discover and characterize asteroids and comets. The mission’s primary objective is to find the majority of objects large enough to cause severe regional impact damage (>140 m ...

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.

Photometric observations of 9 Near-Earth Objects [PDF]

open access: bronze, 2001
We present new CCD observations of nine Near-Earth Asteroids carried out between February, 1999 and July, 2000. The bulk of the data was acquired through an R_C filter, while the minor planet 11405 was observed without filter.

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 ...

Spacewatch Astrometry and Photometry of Near-Earth Objects [PDF]

open access: bronzeSymposium - International Astronomical Union, 2015
The Spacewatch program at the University of Arizona has pioneered automatic methods of detecting Near Earth Objects. Our software presently includes three modes of object detection: automatic motion identification; automatic streak identification; and visual streak identification. For automatic motion detection at sidereal drift rates, the 4σ detection

Heating of near-Earth objects and meteoroids due to close approaches to the Sun [PDF]

open access: bronze, 2009
It is known that near-Earth objects (NEOs) during their orbital evolution may often undergo close approaches to the Sun. Indeed it is estimated that up to ~70% of them end their orbital evolution colliding with the Sun.

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 ...

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 ...
