Long-Term Stability of Planets in Binary Systems
A simple question of celestial mechanics is investigated: in what regions of phase space near a binary system can planets persist for long times? The planets are taken to be test particles moving in…

The Evolution of Long-Period Comets
We study the evolution of long-period comets by numerical integration of their orbits, a more realistic dynamical approach than the Monte Carlo and analytic methods previously used to study this…

The trajectory, structure and origin of the Chelyabinsk asteroidal impactor
TLDR
An analysis of selected video records of the Chelyabinsk superbolide of 15 February 2013 found that its orbit was similar to the orbit of the two-kilometre-diameter asteroid 86039, to a degree of statistical significance sufficient to suggest that the two were once part of the same object.

Earth’s Trojan asteroid
TLDR
It is established that 2010 TK7 is a Trojan companion of Earth, librating around the leading Lagrange triangular point, L4, whose orbit is stable over at least ten thousand years.

Asteroid 2002 VE68, a quasi-satellite of Venus
The asteroid 2002 VE68 is currently a quasi-satellite of Venus, the first object of this dynamical class to be discovered, and is also the first known co-orbital companion to Venus. Our computations…

The Stability of Planets in the Alpha Centauri System
This paper investigates the long-term orbital stability of small bodies near the central binary of the Alpha Centauri system. Test particles on circular orbits are integrated in the field of this…
