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

Weak S-type asteroids compared to C-type explain the observed size distribution of the main belt

Astronomy & Astrophysics
The main belt, the region between the orbits of Mars and Jupiter, is home to more than 1 million asteroids. These asteroids form orbital groups, (i.e., asteroid families formed by collisions) and also spectral groups (taxonomies) with different chemical ...

Lucy L′Ralph In-flight Calibration and Results at (152830) Dinkinesh

The Planetary Science Journal
The L’Ralph instrument is a key component of NASA’s Lucy mission, intended to provide spectral image data of multiple Jupiter Trojans. The instrument operates from ∼0.35 to 4 μ m using two focal plane assemblies: a 350–950 nm multispectral imager, Multi ...

Basaltic asteroids in the middle and outer main belt

, 2022
Up to now, only (4) Vesta has been thought of as a source of differentiated material, which has been discovered all around the Main Belt region. However, the investigations have shown that the objects, with the same spectral properties of Vesta and ...

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 ...

Synergistic approach of asteroid exploitation and planetary protection [PDF]

, 2012
The asteroid and cometary impact hazard has long been recognised as an important issue requiring risk assessment and contingency planning. At the same time asteroids have also been acknowledged as possible sources of raw materials for future large-scale ...

Infrared Colors of Small Serendipitously Found Asteroids in the UKIRT Hemisphere Survey

The Astronomical Journal
The UKIRT Hemisphere Survey covers the northern sky in the infrared from 0° to 60° decl. Current data releases include both J and K bands, with H -band data forthcoming. Here, we present a novel pipeline to recover asteroids from this survey data.

Thermal-IR Observations of (152830) Dinkinesh during the Lucy Mission Flyby

The Planetary Science Journal
NASA’s Lucy spacecraft flew by the main-belt asteroid (152830) Dinkinesh on 2023 November 1, providing a test of its instruments and systems prior to its encounters with the Jupiter Trojans and enabling an opportunity for scientific investigation of this

Near-Earth asteroids in main belt-crossing orbits

Astronomy & Astrophysics
Aims. We study the dynamical and collisional evolution of Near-Earth asteroids (NEAs) in main belt-crossing orbits (NEACs). Methods. We selected NEACs with H

Orbits of the Asteroids Discovered at the Molėtai Observatory in 2000–2004

Open Astronomy, 2014
The paper presents statistics of the asteroids observed and discovered at the Molėtai Observatory, Lithuania in 2000–2004 within the project for astrometric observations of the near-Earth objects (NEOs), the main belt asteroids and comets.
