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

Strong Nongravitational Accelerations and the Potential for Misidentification of Near-Earth Objects
The Astrophysical JournalNongravitational accelerations in the absence of observed activity have recently been identified on near-Earth objects (NEOs), opening the question of the prevalence of anisotropic mass loss in the near-Earth environment.

Search for design solutions to prevent the Kessler effect [PDF]
E3S 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
The 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
The 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
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,

Detect-and-describe: Joint learning framework for detection and description of objects [PDF]
, 2022 Traditional object detection answers two questions; "what" (what the object is?) and "where" (where the object is?). "what" part of the object detection can be fine-grained further i.e. "what type", "what shape" and "what material" etc. This results in the shifting of the object detection tasks to the object description paradigm.

Measuring the Orbit Drift of Near-Earth Asteroids by the Yarkovsky Effect
The Astrophysical Journal, 2023 The Yarkovsky effect causes the semimajor axis drift of near-Earth asteroids. The drift can be detected by a precise orbit determination process. Using the proposed algorithm, 2233 out of 27,078 near-Earth asteroids are chosen as the initial candidates ...
