Possibility of collision between co-orbital asteroids and the Earth
(2005-01-01)
Considering hypothetical co-orbital asteroids with the Earth, Tatum (1997) presented a study about the necessary radial distance in order to produce collision. He adopted an analysis considering a composition of circular ...
PECULIAR EUPHROSYNE
(Iop Publishing Ltd, 2014-09-01)
The asteroid (31) Euphrosyne is the largest body of its namesake family, and it contains more than 99% of the family mass. Among large asteroid families, the Euphrosyne group is peculiar because of its quite steep ...
Formas de equilíbrio e geologia de objetos transnetunianos
(Universidade Tecnológica Federal do ParanáCuritibaBrasilPrograma de Pós-Graduação em Física e AstronomiaUTFPR, 2020-04-15)
Transneptunian Objects (TNOs) are small bodies of the Solar System; they can be seen as spinning bodies under the influence of self-gravity, spin-related forces and tidal forces, classically considered to have fluid behaviour ...
Determinação do período de rotação de alguns asteróides através de observações fotométricas

Mapping the density of particles over the surface of asteroid (101955) Bennu
(2017-01-01)
In the present work we study the motion of particles near the surface of Bennu. An application of the results is to give assistance for the selection of the sample site. Considering the gravitational potential given by the ...
DETECTION of the YORP EFFECT for SMALL ASTEROIDS in the KARIN CLUSTER
(2016-06-01)
The Karin cluster is a young asteroid family thought to have formed only ≃ 5.75 Myr ago. The young age can be demonstrated by numerically integrating the orbits of Karin cluster members backward in time and showing the ...
The influence of Ceres on the dynamical evolution of the Zdenekhorsky/Nemesis asteroid family
(2019-01-01)
The Nemesis family, also identified as the Zdenekhorsky family by some authors, is an “incomplete” asteroid family in the central main belt, characterized by an asymmetric distribution between its left and right side, with ...
On the age of the Nele asteroid family
(Oxford Univ Press, 2018-06-01)
The Nele group, formerly known as the Iannini family, is one of the youngest asteroid families in the main belt. Previously, it has been noted that the pericentre longitudes (omega) over bar and nodal longitudes Omega of ...
