FAST ROTATION OF A SUBKILOMETER-SIZED NEAR-EARTH OBJECT 2011 XA3 [PDF]

open access: yes, 2014
We present light curve observations and their multiband photometry for near-Earth object (NEO) 2011 XA3. The light curve has shown a periodicity of 0.0304 ± 0.0003 days (= 43.8 ± 0.4 minutes).

FEATURES OF KOTLIN ORBIT ESTIMATION LIBRARY

open access: yesOdessa Astronomical Publications, 2018
Since the launch of Sputnik 1, the number of objects in near-earth orbit has been constantly increasing. The growth of number of these objects increases the risk of their collisions with existing satellites and ones which will be launched, that can be ...

Nuclear and Orbital Characterization of the Transition Object (4015) 107P/Wilson–Harrington

open access: yesThe Planetary Science Journal, 2023
Comet 107P/Wilson–Harrington, cross-listed as asteroid 4015, is one of the original transition objects whose properties do not neatly fit into a cometary or asteroidal origin.

New Tools for the Optimized Follow-Up of Imminent Impactors

open access: yesUniverse, 2021
The solar system is populated with, other than planets, a wide variety of minor bodies, the majority of which are represented by asteroids. Most of their orbits are comprised of those between Mars and Jupiter, thus forming a population named Main Belt ...

O2O-Afford: Annotation-Free Large-Scale Object-Object Affordance Learning [PDF]

open access: yesarXiv, 2021
Contrary to the vast literature in modeling, perceiving, and understanding agent-object (e.g., human-object, hand-object, robot-object) interaction in computer vision and robotics, very few past works have studied the task of object-object interaction, which also plays an important role in robotic manipulation and planning tasks.

The Space Complexity of Consensus from Swap [PDF]

open access: yesarXiv, 2023
Nearly thirty years ago, it was shown that $\Omega(\sqrt{n})$ registers are needed to solve obstruction-free consensus among $n$ processes. This lower bound was improved to $n$ registers in 2018, which exactly matches the best upper bound. The $\Omega(\sqrt{n})$ space complexity lower bound actually applies to a class of objects called historyless ...

Adventures in Near-Earth Object Exploration [PDF]

open access: yesScience, 2006
Asteroids, because of the hazard they pose to Earth, are compelling targets for robotic and human space exploration. Yet because of their exotic low-gravity environment, simply landing on an asteroid appears to be much more challenging than we had appreciated 5 or 10 years ago.

Object Preserving Siamese Network for Single Object Tracking on Point Clouds [PDF]

open access: yesarXiv, 2023
Obviously, the object is the key factor of the 3D single object tracking (SOT) task. However, previous Siamese-based trackers overlook the negative effects brought by randomly dropped object points during backbone sampling, which hinder trackers to predict accurate bounding boxes (BBoxes).

Origin and dynamics of Near Earth Objects

open access: yesComptes Rendus. Physique, 2005
Abstract The population of Near-Earth Objects (NEOs) evolves on orbits which can cross the orbit of the Earth. Most NEOs come from the asteroid belt via unstable zones associated with powerful or diffusive resonances. Their evolutionary paths and the statistical properties of their dynamics have been determined by massive numerical integrations.
