A large fraction of ~100 km class low-inclination objects in the classical Kuiper Belt (KB) are binaries with comparable masses and a wide separation of components. A favored model for their formation is that they were captured during the coagulation growth of bodies in the early KB. However, recent studies have suggested that large, 100 km objects can rapidly form in the protoplanetary disks when swarms of locally concentrated solids collapse under their own gravity. Here, we examine the…

Trans-Neptunian binaries as evidence for planetesimal formation by the streaming instability
A critical step toward the emergence of planets in a protoplanetary disk is the accretion of planetesimals, bodies 1–1,000 km in size, from smaller disk constituents. This process is poorly
Kuiper belt: Formation and evolution
Abstract This chapter reviews accretion models for Kuiper belt objects (KBOs), discussing in particular the compatibility of the observed properties of the KBO population with the streaming
Binary survival in the outer solar system
Abstract As indicated by their special characteristics, the cold classical Kuiper belt objects (KBOs) formed and survived at ≃42–47 au. Notably, they show a large fraction of equal-size binaries
Binary Planetesimal Formation from Gravitationally Collapsing Pebble Clouds
Planetesimals are compact astrophysical objects roughly 1–1000 km in size, massive enough to be held together by gravity. They can grow by accreting material to become full-size planets.
Retention of a Primordial Cold Classical Kuiper Belt in an Instability-Driven Model of Solar System Formation
The cold classical population of the Kuiper Belt exhibits a wide variety of unique physical characteristics, which collectively suggest that its dynamical coherence has been maintained throughout the
Using the density of Kuiper Belt Objects to constrain their composition and formation history.
TLDR
This model suggests that coagulation, and not gravitational collapse, was the dominant mechanism for KBO formation, and is used to make predictions for the density of Makemake, 2007 OR10, and MU69.
COLLISIONAL EVOLUTION OF ULTRA-WIDE TRANS-NEPTUNIAN BINARIES
The widely separated, near-equal mass binaries hosted by the cold classical Kuiper Belt are delicately bound and subject to disruption by many perturbing processes. We use analytical arguments and
USING KUIPER BELT BINARIES TO CONSTRAIN NEPTUNE'S MIGRATION HISTORY
Approximately 10‐20% of all Kuiper belt objects (KBOs) occupy mean-motion resonances with Neptune. This dynamical configuration likely resulted from resonance capture as Neptune migrated outward
On the Formation of Planetesimals Via Secular Gravitational Instabilities with Turbulent Stirring
We study the gravitational instability (GI) of small solids in a gas disk as a mechanism to form planetesimals. Dissipation from gas drag introduces secular GI, which proceeds even when standard GI
An alternative origin for debris rings of planetesimals
Core accretion (CA), the most widely accepted scenario for planet formation, postulates existence of ∼ km-sized solid bodies, called planetesimals, arranged in a razor-thin disc in the earliest

FORMATION OF KUIPER BELT BINARIES
The discovery that a substantial fraction of Kuiper Belt objects (KBOs) exists in binaries with wide separations and roughly equal masses has motivated a variety of new theories explaining their
Formation of Kuiper-belt binaries by dynamical friction and three-body encounters
TLDR
It is shown that a transient binary forms when two large bodies penetrate one another's Hill sphere (the region where their mutual forces are larger than the tidal force of the Sun) and the loss of energy needed to stabilize the binary orbit can occur through dynamical friction from surrounding small bodies, or through the gravitational scattering of a third large body.
The formation of Kuiper-belt binaries through exchange reactions
TLDR
The only required assumption is that the TNOs were initially formed through gravitational instabilities in the protoplanetary dust disk, and the basis of the mechanism is an exchange reaction in which a binary whose primary component is much more massive than the secondary interacts with a third body, whose mass is comparable to that of the primary.
Formation of Kuiper-belt binaries through multiple chaotic scattering encounters with low-mass intruders
The discovery that many trans-Neptunian objects exist in pairs, or binaries, is proving invaluable for shedding light on the formation, evolution and structure of the outer Solar system. Based on
The ratio of retrograde to prograde orbits: a test for Kuiper Belt binary formation theories
With the discovery of Kuiper Belt binaries that have wide separations and roughly equal masses, new theories were proposed to explain their formation. Two formation scenarios were suggested by

Abstract Our goal is to understand primary accretion of the first planetesimals. Some examples are seen today in the asteroid belt, providing the parent bodies for the primitive meteorites. The
The binary Kuiper-belt object 1998 WW31
TLDR
It is reported that the Kuiper-belt object 1998 WW31 is binary with a highly eccentric orbit (eccentricity e ≈ 0.8) and a long period (about 570 days), very different from the Pluto/Charon system, which was hitherto the only previously known binary in theKuiper belt.

We outline a scenario that traces a direct path from freely floating nebula particles to the first 10-100 km sized bodies in the terrestrial planet region, producing planetesimals that have
Rapid planetesimal formation in turbulent circumstellar disks
TLDR
It is reported that boulders can undergo efficient gravitational collapse in locally overdense regions in the midplane of the disk, and it is found that gravitationally bound clusters form with masses comparable to dwarf planets and containing a distribution of boulder sizes.
