Challenge in Arrokoth’s Single Merger to Achieve the Shape’s Principal Axis Configuration

The Planetary Science Journal
The cold-classical Kuiper Belt Object 486958 Arrokoth is a contact binary composed of two flattened lobes, Weeyo and Wenu, closely aligned along their principal axes, despite each lobe having a highly irregular shape.

Occultations by Kuiper belt objects.

, 1997
Objects in the Kuiper belt are small and far away thus difficult to study in detail even with the best telescopes available at earth. For much of the early history of the Kuiper belt, studies of the compositions of the objects were relegated to ...

Spectral Characterization of the Organic- and Methanol-rich Cliff-type Trans-Neptunian Objects

The Astronomical Journal
Trans-Neptunian objects (TNOs) harbor pristine materials from the early solar system. The James Webb Space Telescope offers major insights into the spectral classification of these small bodies.

Rotational Study of 5:3 and 7:4 Resonant Objects within the Main Classical Trans-Neptunian Belt

The Planetary Science Journal
The 5:3 and 7:4 mean motion resonances of Neptune are at 42.3 and 43.7 au, respectively, and overlap with objects in the classical trans-Neptunian belt (Kuiper Belt).

On Error Estimates for Hapke Photometric Model Parameters from Disk-integrated Phase Curves of Airless Planetary Bodies

The Planetary Science Journal
The Hapke bidirectional reflectance model is widely used to analyze photometric observations of planetary surfaces. When fitting disk-integrated data, nonuniqueness concerns arise if observations lack sufficient phase angle coverage to constrain the ...

Cosmic Ray Mantle Visibility on Kuiper Belt Objects

, 2006
Optically red objects constitute the dynamically cold, old component of the Classical Kuiper Belt (40 - 47 AU) with heliocentric orbits of low eccentricity and inclination.

The Radial Distribution of the Kuiper Belt [PDF]

, 2001
We examine the radial distribution of the Kuiper Belt objects (KBOs) using a method that is insensitive to observational bias effects. This technique allows the use of the discovery distances of all KBOs, independent of orbital classification or ...

Stellar Occultations by Trans-Neptunian Object Satellites: Predictions and Observations

The Planetary Science Journal
With the great success of stellar occultations in probing trans-Neptunian objects (TNOs), these observations have become ubiquitous, leading to significant advances in our knowledge of TNOs. As stellar occultation predictions have improved, it has become

Numerical Investigation of the Cohesive Strength Regime of the Bilobated Arrokoth after the Sky-crater-forming Impact Event

The Planetary Science Journal
In 2019, NASA’s New Horizons mission, using the Long Range Reconnaissance Imager, revealed Arrokoth’s bilobated shape and a large impact-crater-like region (“Sky”) on the small lobe, which is ∼7 km wide and ∼1 km deep. Given that this depression takes up
