We present a new analysis of the currently available orbital elements for the known Kuiper belt objects. In the nonresonant, main Kuiper belt, we find a statistically significant relationship between an object's absolute magnitude (H) and its inclination (i). Objects with H < 6.5 (i.e., radii ≳170 km for a 4% albedo) have higher inclinations than those with H > 6.5 (radii ≲170 km). We have shown that this relationship is not caused by any obvious observational bias. We argue that the main… 

The Relationship Between KBO Colors and Kuiper-belt Plane Inclination

A large population of small, icy bodies orbits the sun just beyond Neptune, known as the Kuiper Belt. These objects, thought to be the progenitors of short period comets, could provide a sample of


Using data from the Deep Ecliptic Survey (DES), we investigate the inclination distributions of objects in the Kuiper Belt. We present a derivation for observational bias removal and use this

The Inclination Distribution of the Kuiper Belt

We develop a general method for determining the unbiased inclination distribution of the Kuiper belt using only the inclination and latitude of discovery of known Kuiper belt objects (KBOs). These

The secular evolution of the Kuiper belt after a close stellar encounter

We show the effects of the perturbation caused by a passing by star on the Kuiper belt objects (KBOs) of our Solar system. The dynamics of the Kuiper belt (KB) is followed by direct N-body

The Kuiper Belt and the Primordial Evolution of the Solar System

We discuss the structure of the Kuiper belt as it can be inferred from the first decade of observations. In particular, we focus on its most intriguing properties — the mass deficit, the

Colors and Spectra of Kuiper Belt Objects

We present new measurements of the optical colors of Kuiper belt objects, principally from the Keck 10 m telescope. The measurements confirm the existence of a wide spread in the B-V, V-R, and R-I


We reexamine the correlation between the colors and the inclinations of the Classical Kuiper Belt Objects (CKBOs) with an enlarged sample of optical measurements. The correlation is strong (ρ = −0.7)

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

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.

P417 Evidence for early stellar encounters in the orbital distribution of Edgeworth-Kuiper Belt objects

We show that early stellar encounters can explain the high eccentricities and inclinations observed in the outer part (>42 AU) of the Edgeworth-Kuiper Belt (EKB). We consider the proto-Sun as a

On the Collisional Environment, Accretion Time Scales, and Architecture of the Massive, Primordial Kuiper Belt.

ii Abstract Previous collisional modelling has suggested that the mass of the primordial Kuiper Disk between 30 and 50 AU was probably of order 10M to 50M. We explore the consequences of a massive,

Collisional Erosion in the Primordial Edgeworth-Kuiper Belt and the Generation of the 30-50 AU Kuiper Gap

One of the oustanding questions about the architecture of the outer solar system is how the trans-Neptunian disk of comets and small planet-scale objects known as the solar system's Edgeworth-Kuiper

A disk of scattered icy objects and the origin of Jupiter-family comets.

Two recently discovered objects, 1996 RQ20 and 1996 TL66, have orbital elements similar to those predicted for objects in this disk, suggesting that they are thus far the only members of this disk to be identified.

The origin of Pluto's orbit: implications for the

The origin of the highly eccentric, inclined, and resonance-locked orbit of Pluto has long been a puzzle. A possible explanation has been proposed recently which suggests that these extraordinary

Large Scattered Planetesimals and the Excitation of the Small Body Belts

Abstract We study the dynamical excitation that large planetesimals, scattered either by Neptune or Jupiter, could have provided to the primordial Edgeworth–Kuiper belt and the asteroid belt. Using

The Gravitational Sculpting of the Kuiper Belt

Results are presented of numerical integrations over billion year time scales of the orbital evolution of more than one thousand test particles on initially low-inclination, low-eccentricity orbits
