The Near-Earth Object Surveyor Mission [PDF]
The 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 ...

Near-Earth object hazardous impact: A Multi-Criteria Decision Making approach. [PDF]
Sci Rep, 2016 The impact of a near-Earth object (NEO) may release large amounts of energy and cause serious damage. Several NEO hazard studies conducted over the past few years provide forecasts, impact probabilities and assessment ratings, such as the Torino and ...

Unconfirmed Near-Earth Objects [PDF]
The 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 ...

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

Near-infrared polarimetric study of near-Earth object 252P/LINEAR: an implication of scattered light from the evolved dust particles [PDF]
Astronomy & Astrophysics, 2019 Context. Comets undergo resurfacing due to solar radiation, while their primordial interiors remain unchanged. Multi-epoch observations of comets enable us to characterize a change in sublimation pattern as a function of heliocentric distance, which in ...

Are Near Earth Objects the Key to Optimization Theory? [PDF]
British Journal of Mathematics & Computer Science, 2009 This note suggests that near earth objects and Central Force Optimization have something in common, that NEO theory may hold the key to solving some vexing problems in deterministic optimization: local trapping and proof of convergence. CFO analogizes Newton's laws to locate the global maxima of a function.

High-fidelity Simulations of the Near-Earth Object Search Performance of the Large Synoptic Survey Telescope [PDF]
, 2017 We perform high-fidelity simulations of a wide-field telescopic survey searching for Near-Earth Objects (NEOs) larger than 140 m, focusing on the observation and detection model, as well as detection efficiency and accuracy.

Searching for the first near-Earth object family [PDF]
Icarus, 2012 We report on our search for genetically related asteroids amongst the near-Earth object (NEO) population - families of NEOs akin to the well known main belt asteroid families. We used the technique proposed by Fu et al. (2005) supplemented with a detailed analysis of the statistical significance of the detected clusters. Their significance was assessed

Directed energy active illumination for near-Earth object detection
Optics & Photonics - Optical Engineering + Applications, 2014 On 15 February 2013, a previously unknown ~20 m asteroid struck Earth near Chelyabinsk, Russia, releasing kinetic energy equivalent to ~570 kt TNT. Detecting objects like the Chelyabinsk impactor that are orbiting near Earth is a difficult task, in part ...
