Keck and Gemini Characterization of Hayabusa2# Rendezvous Target 1998 KY26

The Astronomical Journal
Near-Earth object (NEO) 1998 KY _26 is a target of the Hayabusa2# spacecraft, which it will rendezvous with in 2031 July. The asteroid has been noted to rotate rapidly and has a large out-of-plane nongravitational acceleration.

Geography of the asteroid belt [PDF]

The CSM classification serves as the starting point on the geography of the asteroid belt. Raw data on asteroid types are corrected for observational biases (against dark objects, for instance) to derive the distribution of types throughout the belt ...

Origin of asteroid (469219) Kamo‘oalewa: The main asteroid belt or the Giordano Bruno crater on the Moon?

Astronomy & Astrophysics
Context. Asteroid (469219) Kamo‘oalewa is the target of the Tianwen-2 sample-return mission by the China National Space Administration. Because of its orbit and its peculiar spectral properties, it was proposed that Kamo‘oalewa originated from the Moon ...

Collaborative asteroid photometry of six main-belt asteroids

, 2022
Synodic rotation periods of six main-belt asteroids were derived from photometric observations obtained from 2021 July 21 through November 2 from three observatories situated in Malta and one from Spain. We provide lightcurve rotation periods for (1713) Banchilon, (2232) Altaj, (2458) Veniakaverin, (6681) Prokopovich, (6787) 1991 PF15, and (18863) 1999

Geochemical Modeling from the Asteroid Belt to the Kuiper Belt: Systematic Review

Encyclopedia
The high costs and time-consuming nature of space exploration missions are among the major barriers to studying deep space. The lack of samples and limited information make such studies challenging, highlighting the need for innovative solutions ...

Pulsar Timing Noise from Brownian Motion of the Sun

The Astrophysical Journal Letters
Recently, pulsar timing arrays (PTAs) reported a signal at nanohertz frequencies consistent with a stochastic gravitational-wave background. Here, I show that the Brownian motion of the Sun as a result of its random gravitational interactions with the ...

Satellite Formation around the Largest Asteroids

The Astrophysical Journal Letters
Satellites around large asteroids are preferentially found among those with the most rapid rotation and elongated shape. The taxonomic statistics are similarly skewed; in total, 13 asteroids larger than 100 km are known to have satellites, but none have ...

Surface Clutter Separation for Asteroid Radar Imaging in the Tianwen-2 Mission

The Astronomical Journal
The Tianwen-2 probe carries an asteroid core-scanning radar (ACSR) to study the internal structures of near-Earth asteroid 2016 HO _3 and main-belt comet 311P.
