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
A possible long-lived belt of objects between Uranus and Neptune
Recent discoveries of objects orbiting beyond Neptune have emphasized that our understanding of the distribution and dynamics of material in the outer Solar System is very incomplete. This
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
TLDR
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
Extremely red Kuiper-belt objects in near-circular orbits beyond 40  AU
TLDR
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.
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
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
Chaotic motion in a primordial comet disk beyond Neptune and comet influx to the Solar System
CHAOTIC dynamics, characterized by extremely sensitive dependence on initial conditions with exponential divergence of neighbouring trajectories and subsequent loss of predictability1, have recently
Extraordinary colors of asteroidal object (5145) 1992 AD
Abstract The recently discovered outer Solar System object, (5145) 1992 AD, in a somewhat Chiron-like orbit, has colors far redder than any other known asteroids or comets, and represents a
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

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
High resolution surface brightness profiles of near-earth asteroids
Abstract We present a new method to search for and estimate mass loss in near-Earth asteroids (NEAs) using high resolution surface photometry. The method was applied to 11 NEAs observed with a
