Evaluation of a Laser Altimeter using the Pseudo-Random Noise Modulation Technique for Apophis Mission [PDF]
Journal of Astronomy and Space Sciences, 2021 Apophis is a near-Earth object with a diameter of approximately 340 m, which will come closer to the Earth than a geostationary orbit in 2029, offering a unique opportunity for characterizing the object during the upcoming encounter.

Infrared Light Curves of Near-Earth Objects [PDF]
The Astrophysical Journal Supplement Series, 2018 Abstract We present light curves and derive periods and amplitudes for a subset of 38 near-Earth objects (NEOs) observed at 4.5 μm with the IRAC camera on the the Spitzer Space Telescope, many of them having no previously reported rotation periods. This subset was chosen from about 1800 IRAC NEO observations as having obvious periodicity

From Discovery to Impact - Near Earth Asteroids
Geoinformatics FCE CTU, 2012 The Near-Earth Objects (NEOs) are the most important of the small bodies of the solar system, having the capability of close approaches to the Earth and the chance to collide with the Earth.

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

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

Frontiers in Astronomy and Space Sciences, 2022 The observation of small bodies in the Space Environment is an ongoing important task in astronomy. While nowadays new objects are mostly detected in larger sky surveys, several follow-up observations are usually needed for each object to improve the ...

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
