The Astronomical Journal, 2022 Within the dynamically cold low-inclination portion of the Classical Kuiper Belt, there exists a population of weakly bound binary systems with a number of unusual properties, most notable of which is their extremely wide orbital separations—beyond 7% of

Modified Newtonian Dynamics as an Alternative to the Planet Nine Hypothesis
The Astronomical Journal, 2023 A new class of Kuiper Belt objects (KBOs) that lie beyond Neptune with semimajor axes greater than 250 astronomical units show orbital anomalies that have been interpreted as evidence for an undiscovered ninth planet.

A HYPOTHESIS FOR THE COLOR DIVERSITY OF THE KUIPER BELT [PDF]
The Astrophysical Journal, 2011 We propose a chemical and dynamical process to explain the surface colors of the Kuiper belt. In our hypothesis, the initial bulk compositions of the bodies themselves can be quite diverse -- as is seen in comets -- but the early surface compositions are set by volatile evaporation after the objects are formed.

The shape distribution of Kuiper belt objects
, 2003 . If we assume that the periodic brightness variations in a Kuiper Belt lightcurve are determined only by their aspherical shapes and the observing geome-try, the fraction of detectable Kuiper Belt lightcurves and the lightcurve amplitude distribution ...

Journal of Field Robotics, Volume 43, Issue 7, Page 4475-4514, October 2026.ABSTRACT As a crucial puzzle piece of deep space exploration, exploring small bodies can provide significant scientific insights and valuable mineral resources. Unlike missions to the Moon and Mars, small‐body missions pose distinct technical challenges, including communication delays, weak gravity, and uncertain environments. This paper reviews a full

Ferric Chloride: The Venusian Unknown UV Absorber?
Journal of Geophysical Research: Planets, Volume 131, Issue 9, September 2026.Abstract Near‐ultraviolet imaging of the planet Venus reveals inhomogeneous absorption features in the otherwise bright clouds. This absorption has been studied for nearly 100 years, but identification of the near‐UV absorber remains one of the largest open questions in Venusian research.

Col-OSSOS: The Two Types of Kuiper Belt Surfaces
The Planetary Science Journal, 2023 The Colors of the Outer Solar System Origins Survey (Col-OSSOS) has gathered a high-quality, near-simultaneous, and brightness-complete sample of ( g − r ) and ( r − J ) colors for 102 Kuiper Belt objects (KBOs) with ( u − g ) and ( r − z ) gathered for ...

Journal of Geophysical Research: Planets, Volume 131, Issue 9, September 2026.Abstract Water ice is an important rock‐forming mineral, both on the Earth and on various extraterrestrial bodies. Naturally occurring ice is often “dirty”–an intimate mixture with harder mineral grains, which can have significant effects on the bulk properties of the aggregate. We have used neutron powder diffraction, with in situ triaxial deformation,
