Machine learning techniques for classifying dangerous asteroids [PDF]
MethodsX, 2023 There is an infinite number of objects in outer space, and these objects and asteroids might be harmful. Hence, it is wise to know what is surrounding us and what can harm us amongst those.Therefore, in this article, with the hyperparameters tuning of ...

Numerical simulations suggest asteroids (101955) Bennu and (162173) Ryugu are likely second or later generation rubble piles [PDF]
Nature CommunicationsRubble pile asteroids are widely understood to be composed of reaccumulated debris following a catastrophic collision between asteroids in the main asteroid belt, where each disruption can make a family of new asteroids.

Deficit of primitive compositions in binary asteroids and pairs [PDF]
A&A 672, A48 (2023), 2023 Context. Small binary asteroid systems and pairs are thought to form through fission induced by spin up via the Yarkovsky-O'Keefe-Radzievskii-Paddack (YORP) effect. This process is expected to depend on their structural strength, hence composition. Aims.

Gravity-Assist might be a Solution to Save Earth from Global Warming [PDF]
Iranian Journal of Astronomy and Astrophysics, 2023 Global warming is one of the problems of human civilization and decarbonization policy is the main solution to this problem. In this work, we propose an alternative method of using the gravity assist by the asteroids to increase the orbital distance of ...

Rotation Periods of Asteroids Determined With Bootstrap Convex Inversion From ATLAS Photometry
Frontiers in Astronomy and Space Sciences, 2022 The rotation period is one of the fundamental physical characteristics of asteroids. It can be determined from photometric measurements by standard methods of time-series period analysis or by creating a physical model of an asteroid with the rotation ...

Comparison of Asteroids Observed in the SDSS with a Catalog of Known Asteroids [PDF]
Astron.J.124:1776,2002, 2002 We positionally correlate asteroids from existing catalogs with a sample of $\about$18,000 asteroids detected by the Sloan Digital Sky Survey (SDSS, Ivezi\'{c} {\em et al.} 2001). We find 2641 unique matches, which represent the largest sample of asteroids with both accurate multi-color photometry and known orbital parameters.
