Radar observability of near-Earth objects using EISCAT 3D [PDF]
Annales Geophysicae, 2020 Radar observations can be used to obtain accurate orbital elements for near-Earth objects (NEOs) as a result of the very accurate range and range rate measureables.

The Yarkovsky Drift's Influence on NEAs: Trends and Predictions with NEOWISE Measurements [PDF]
, 2012 We used WISE-derived geometric albedos (p_V) and diameters, as well as geometric albedos and diameters from the literature, to produce more accurate diurnal Yarkovsky drift predictions for 540 near-Earth asteroids (NEAs) out of the current sample of \sim

Klet Observatory – European Contribution to Detecting and Tracking of Near Earth Objects
Geoinformatics FCE CTU, 2012 Near Earth Object (NEO) research is an expanding field of astronomy. Is is important for solar system science and also for protecting human society from asteroid and comet hazard. A near-Earth object (NEO) can be defined as an asteroid or comet that has

First Results from the rapid-response spectrophotometric characterization of Near-Earth Objects [PDF]
, 2019 As part of our multi-observatory, multi-filter campaign, we present \rmi color observations of 82 Near-Earth Objects (NEOs) obtained with the RATIR instrument on the 1.5m robotic telescope at the San Pedro Martir's National Observatory in Mexico.

Identifying near-Earth object families
Icarus, 2005 The study of asteroid families has provided tremendous insight into the forces that sculpted the main belt and continue to drive the collisional and dynamical evolution of asteroids. The identification of asteroid families within the NEO population could provide a similar boon to studies of their formation and interiors.

WORKING GROUP: NEAR-EARTH OBJECTS [PDF]
Proceedings of the International Astronomical Union, 2011 Following its meeting in May, 2010, the IAU Executive Committee requested that a Working Group on NEOs within Div. III be re-activated and carry out the following activities: a) investigate and formulate requirements for an international ground- and/or space-based NEO survey, to detect, track and characterize (optical/IR, radar) 90% of all

Easily retrievable objects among the NEO population [PDF]
, 2013 Asteroids and comets are of strategic importance for science in an effort to understand the formation, evolution and composition of the Solar System. Near-Earth Objects (NEOs) are of particular interest because of their accessibility from Earth, but also

A Constellation of MicroSats to Search for NEOs
, 2018 Large or even medium sized asteroids impacting the Earth can cause damage on a global scale. Existing and planned concepts for finding near-Earth objects (NEOs) with diameter of 140 m or larger would take ~15-20 years of observation to find ~90% of them.
