The formation of the largest objects in the Kuiper belt, with measured densities of ∼1.5 g cm−3 and higher, from the coagulation of small bodies, with measured densities below 1 g cm−3, is difficult to explain without invoking significant porosity in the smallest objects. If such porosity does occur, measured densities should begin to increase at the size at which significant porosity is no longer supported. Among the asteroids, this transition occurs for diameters larger than ∼350 km. In the…

The Density of Mid-sized Kuiper Belt Objects from ALMA Thermal Observations

The densities of mid-sized Kuiper Belt objects (KBOs) are a key constraint in understanding the assembly of objects in the outer solar system. These objects are critical for understanding the

Interpreting the densities of the Kuiper belt's dwarf planets

Kuiper Belt objects with absolute magnitude less than 3 (radius $\gtrsim$500 km), the dwarf planets, have a range of different ice/rock ratios, and are more rock-rich than their smaller counterparts.

Mass of the Kuiper belt

The Kuiper belt includes tens of thousand of large bodies and millions of smaller objects. The main part of the belt objects is located in the annular zone between 39.4 and 47.8 au from the Sun; the

Medium-sized Satellites of Large Kuiper Belt Objects

While satellites of mid- to small-Kuiper Belt objects tend to be similar in size and brightness to their primaries, the largest Kuiper Belt objects preferentially have satellites with small

The Contribution of Dwarf Planets to the Origin of Jupiter Family Comets

We explore the long-term evolution of a bias-free orbital representation of the cometary nuclei (with diameters above 2 km) of the Kuiper Belt, using the so-called L7 synthetic model from CFEPS,

Kuiper belt: Formation and evolution

Growth of asteroids, planetary embryos, and Kuiper belt objects by chondrule accretion

TLDR
It is shown that the main growth of asteroids can result from gas drag–assisted accretion of chondrules, and planetesimal accretion and chondrule accretion play more equal roles in the formation of Moon-sized embryos in the terrestrial planet formation region.

Geophysical evidence that Saturn’s Moon Phoebe originated from a C-type asteroid reservoir

Saturn’s Moon Phoebe has been suggested to originate from the Kuiper Belt. However, its density is twice that of Kuiper Belt objects (KBOs) in the same size class, which challenges that

The Albedo, Size, and Density of Binary Kuiper Belt Object (47171) 1999 TC36

We measured the system-integrated thermal emission of the binary Kuiper Belt object (47171) 1999 TC36 at wavelengths near 24 and 70 μm using the Spitzer Space Telescope. We fit these data and the

THE FORMATION OF THE COLLISIONAL FAMILY AROUND THE DWARF PLANET HAUMEA

Haumea, a rapidly rotating elongated dwarf planet (∼1500 km in diameter), has two satellites and is associated with a “family” of several smaller Kuiper Belt objects (KBOs) in similar orbits. All

A collisional family of icy objects in the Kuiper belt

TLDR
The discovery of a family of Kuiper belt objects with surface properties and orbits that are nearly identical to those of 2003 EL61, which appears to be fragments of the ejected ice mantle of2003 EL61.

The Compositions of Kuiper Belt Objects

Objects in the Kuiper belt are difficult to study in detail, even with the best telescopes available. Therefore, for many years, studies of the compositions of these objects were relegated to

Photometric Observations Constraining the Size, Shape, and Albedo of 2003 EL61, a Rapidly Rotating, Pluto-sized Object in the Kuiper Belt

We present measurements at optical wavelengths of the spectral reflectance, rotational light curve, and solar phase curve of 2003 EL61. With apparent visual magnitude 17.5 at 51 AU from the Sun, this

A Pluto-like radius and a high albedo for the dwarf planet Eris from an occultation

TLDR
The observation of a multi-chord stellar occultation by Eris on 6 November 2010 is reported, consistent with a spherical shape for Eris, and it is anticipated that this atmosphere may periodically sublimate as Eris approaches its perihelion, at 37.8 astronomical units from the Sun.

Formation and Collisional Evolution of Kuiper Belt Objects

This chapter summarizes analytic theory and numerical calculations for the formation and collisional evolution of KBOs at 20--150 AU. We describe the main predictions of a baseline self-stirring

The resistance of planetesimals to collisional erosion changes dramatically during planet formation. The transition between accretion and erosion from a collision is defined by the relationship
