Journal ArticleDOI
The asteroid lightcurve database
TL;DR: The Asteroid Lightcurve Database (LCDB) as mentioned in this paper is a central database for asteroid lightcurve data, i.e., rotation rate and amplitude along with ancillary information such as diameter and albedo, taxonomic class, etc.
Journal ArticleDOI
Fast and Slow Rotation of Asteroids
TL;DR: In this paper, the authors present an analysis of the distribution of asteroid spin rates vs. size, and find that significant populations of both slow and fast rotators among asteroids smaller than D =40 km, and especially below 10 km.
Journal ArticleDOI

TL;DR: High-resolution radar images reveal near-Earth asteroid (66391) 1999 KW4 to be a binary system that is dominated by an equatorial ridge at the object's potential-energy minimum and has exotic physical and dynamical properties.

TL;DR: A dedicated search along the approach trajectory recovered 47 meteorites, fragments of a single body named Almahata Sitta, with a total mass of 3.95 kg, identifying the asteroid as F class, now firmly linked to dark carbon-rich anomalous ureilites, a material so fragile it was not previously represented in meteorite collections.

TL;DR: In this article, photometric data on 17 binary near-Earth asteroids (15 of them are certain detections, two are probables) were analyzed and characteristic properties of the near Earth asteroid (NEA) binary population were inferred.
