THE apparent emptiness of the outer Solar System has been a long-standing puzzle for astronomers, as it contrasts markedly with the abundance of asteroids and short-period comets found closer to the Sun. One explanation for this might be that the orbits of distant objects are intrinsically short-lived, perhaps owing to the gravitational influence of the giant planets. Another possibility is that such objects are very faint, and thus they might easily go undetected. An early survey1 designed to… 

A new dynamical class of object in the outer Solar System

Some three dozen objects have now been discovered beyond the orbit of Neptune and classified as members of the Kuiper belt—a remnant population of icy planetesimals that failed to be incorporated

Two distinct populations of Kuiper-belt objects

The discovery of the first member of the Kuiper belt—a formerly hypothetical ancient reservoir of objects located beyond Neptune's orbit—started a revolution in our understanding of the outer Solar

Discovery of a Planetary-sized Object in the Scattered Kuiper Belt

We present the discovery and initial physical and dynamical characterization of the object 2003 UB313. The object is sufficiently bright that for all reasonable values of the albedo it is certain to

The Kuiper Belt

The Kuiper Belt is a swarm of trans-Neptunian objects, including Pluto, which can be broadly regarded as artefacts of the sun’s proto-planetary solar nebula (PPSN). It is considered to be the source

1998 SM165: A large Kuiper belt object with an irregular shape

Observations of the Kuiper belt object 1998 SM165 indicate its brightness periodically varies by 0.56 magnitudes over a 4-h interval, which would put it among the largest elongated objects known in the authors' solar system.

The Existence of a Planet beyond 50 AU and the Orbital Distribution of the Classical Edgeworth–Kuiper-Belt Objects

Abstract We study the effects of a Mars-like planetoid with a semimajor axis at about ∼60 AU orbiting embedded in the primordial Edgeworth–Kuiper belt (EKB). The origin of such an object can be

The Solar System Beyond The Planets

The Kuiper belt contains a vast number of objects in a flattened, ring-like volume beyond the orbit of Neptune. These objects are collisionally processed relics from the accretion disk of the Sun

Extremely red Kuiper-belt objects in near-circular orbits beyond 40  AU

It is reported that all nine of the KBOs in this survey on near-circular (low-eccentricity) orbits with perihelion distances larger than 40 AU have extremely red surfaces, thereby connecting an observable property with a dynamical class.

Pluto and the Kuiper Disk

Only a few years ago, the outer Solar System appeared to be largely empty, inhabited only by the four giant planets, Pluto, and a smallish population of transient comets orbiting among the giant

Planetary perturbations and the origins of short-period comets

To investigate the dynamical plausibility of possible sources for the short-period comets, a representative sample of comet orbits in the field of the sun and the giant planets was integrated, with

Dynamical limits on dark mass in the outer solar system

Simplified model solar systems with known observational errors are considered in conducting a dynamical search for dark mass and its minimum detectable amount, and in determining the significance of

The Origin of Short-Period Comets

The key results of an extensive series of numerical simulations of the evolution of comet orbits due to the gravitational perturbations of the giant planets are presented. The results show that the

Cometary activity in 2060 Chiron

Results of a 2-yr (1988-90) investigation of cometary activity in 2060 Chiron based on CCD photometry and spectroscopy are reported. The photometry observations include a new rotational light curve

Chaotic motion in a comet disk beyond Neptune - The delivery of short-period comets

Recent Monte Carlo simulations have demonstrated that a source with a spherical distribution of orbital angular momenta such as the Oort Cloud cannot give rise to the highly flattened distribution of
