Abstract The asteroids are a major source of potential impactors on the Earth today. It has long been assumed that the giant planet Jupiter acts as a shield, significantly lowering the impact rate on the Earth from both cometary and asteroidal bodies. Such shielding, it is claimed, enabled the development and evolution of life in a collisional environment, which is not overly hostile. The reduced frequency of impacts, and of related mass extinctions, would have allowed life the time to thrive…

Jupiter – friend or foe? III: the Oort cloud comets
Abstract It has long been assumed that the planet Jupiter acts as a giant shield, significantly lowering the impact rate of minor bodies on Earth. However, until recently, very little work had been
Jupiter – friend or foe? IV: the influence of orbital eccentricity and inclination
Abstract For many years, it has been assumed that Jupiter has prevented the Earth from being subject to a punishing impact regime that would have greatly hindered the development of life. Here, we
Quantifying Jupiter's influence on the Earth's impact flux: Implications for planetary habitability
It has long been thought that the presence of a giant planet is a pre-requisite for the development of life on potentially habitable planets. Without Jupiter, it was argued, the Earth would have been
Jupiter: Cosmic Jekyll and Hyde.
The simulations predict that Jupiter's capacity to shield or intercept Earth-bound comets originating in the outer Solar System is poor, and that the importance of jovian planets on the formation of life is not that they act as shields, but rather that they deliver life-enabling volatiles to the terrestrial planets.
The influence of Jupiter, Mars and Venus on Earth’sorbital evolution
Summary: In the coming years, it is likely that the first potentially Earth-like planets will be discovered orbiting other stars. Once found, the characterisation of those planets will play a vital
The role of Jupiter in driving Earth's orbital evolution
In coming years, the first truly Earth-like planets will be discovered orbiting other stars, and the search for signs of life on these worlds will begin. However, such observations will be hugely
Could the Migration of Jupiter Have Accelerated the Atmospheric Evolution of Venus?
In the study of planetary habitability and terrestrial atmospheric evolution, the divergence of surface conditions for Venus and Earth remains an area of active research. Among the intrinsic and
Prospecting for exo-Earths in multiple planet systems with a gas giant
In this work, we hunt for the best places to find exo-Earths in the currently known exoplanet population. While it is still unclear whether Jupiter had a beneficial or detrimental effect on the


Origin and Evolution of Near-Earth Objects
Asteroids and comets on orbits with perihelion distance q 0.983 AU are usually called near-Earth objects (NEOs). It has long been debated whether the NEOs are mostly of asteroidal or cometary origin.

The formation of the gas giant planets Jupiter and Saturn probably required the growth of massive ∼ 15 Earth-mass cores on a time scale shorter than the ∼ 107 time scale for removal of nebular gas, but the probability of similar gas giants occurring in other planetary systems is unclear.
Origin of the cataclysmic Late Heavy Bombardment period of the terrestrial planets
This model not only naturally explains the Late Heavy Bombardment, but also reproduces the observational constraints of the outer Solar System.

Collisions amongst comets create belts of orbiting debris and, by using submillimetre wavelength observations, these collision zones can be imaged around nearby stars. An image of the closest Solar
Debiased Orbital and Absolute Magnitude Distribution of the Near-Earth Objects
The orbital and absolute magnitude distribution of the near-Earth objects (NEOs) is difficult to compute, partly because only a modest fraction of the entire NEO population has been discovered so
Occurrence of Earth-Like Bodies in Planetary Systems
Simulations in which runaways were allowed to form in the asteroid belt show that during the growth of the planets these distributions spontaneously evolve toward those observed, simply as a result of known solar system processes.
Gravitational scattering by giant planets
We seek to characterize giant-planet systems by their gravitational scattering properties. We do this to a given system by integrating it numerically along with a large number of hypothetical small
Impacts on the Earth by asteroids and comets: assessing the hazard
There is a 1-in-10,000 chance that a large (∼2-km diameter) asteroid or comet will collide with the Earth during the next century, disrupting the ecosphere and killing a large fraction of the world's
The evolution of diversity in ancient ecosystems: a review
The pronounced divergence in estimates of origination times of groups as diverse as angiosperms, diatoms and mammals in terms of the fossil record as against molecular data point to the possibilities of protracted intervals of geological time with a cryptic diversity.
The capture of Centaurs as Trojans
Large-scale simulations of Centaurs have yielded vast numbers of data, the analysis of which allows interesting but uncommon scenarios to be studied. One such rare phenomenon is the temporary capture
