Long-Term Stability of Planets in Binary Systems
- M. Holman, P. Wiegert
- Physics
- 1 September 1996
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… Expand
The Evolution of Long-Period Comets
- P. Wiegert, S. Tremaine
- Physics
- 20 May 1997
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… Expand
A meteoroid stream survey using the Canadian Meteor Orbit Radar II: Identification of minor showers using a 3D wavelet transform
- P. Brown, D. K. Wong, R. Weryk, P. Wiegert
- Geology
- 1 May 2010
Abstract A 7 year survey using the Canadian Meteor Orbit Radar (CMOR), a specular backscattering orbital radar, has produced three million individually measured meteoroid orbits for particles with… Expand
The trajectory, structure and origin of the Chelyabinsk asteroidal impactor
- J. Borovička, P. Spurn'y, +4 authors L. Shrbený
- Geology, Medicine
- Nature
- 14 November 2013
Earth is continuously colliding with fragments of asteroids and comets of various sizes. The largest encounter in historical times occurred over the Tunguska river in Siberia in 1908, producing an… Expand
Earth’s Trojan asteroid
- M. Connors, P. Wiegert, C. Veillet
- Physics, Medicine
- Nature
- 28 July 2011
It was realized in 1772 that small bodies can stably share the same orbit as a planet if they remain near ‘triangular points’ 60° ahead of or behind it in the orbit. Such ‘Trojan asteroids’ have been… Expand
On the origin of the unusual orbit of Comet 2P/Encke
- H. Levison, D. Terrell, P. Wiegert, L. Dones, M. Duncan
- Physics
- 1 May 2006
Abstract The orbit of Comet 2P/Encke is difficult to understand because it is decoupled from Jupiter—its aphelion distance is only 4.1 AU . We present a series of orbital integrations designed to… Expand
Stability limits for the quasi-satellite orbit
- S. Mikkola, K. Innanen, P. Wiegert, M. Connors, Ramon Brasser
- Physics
- 11 June 2006
An asteroid moving around the Sun having approximately the same mean motion and mean longitude as a planet, but a different eccentricity, circles the planet like a retrograde satellite even when the… Expand
The Stability of Planets in the Alpha Centauri System
- P. Wiegert, M. Holman
- Physics
- 16 September 1996
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… Expand
A dynamical model of the sporadic meteoroid complex
- P. Wiegert, J. Vaubaillon, M. Campbell-Brown
- Physics
- 1 May 2009
Abstract Sporadic meteoroids are the most abundant yet least understood component of the Earth's meteoroid complex. This paper aims to build a physics-based model of this complex calibrated with five… Expand
Asteroid 2002 VE68, a quasi-satellite of Venus
- S. Mikkola, Ramon Brasser, P. Wiegert, K. Innanen
- Physics
- 1 July 2004
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… Expand
