This image of Dactyl was taken by Galileo on 28 August 1993 from a range of 3900 km. Resolution is about 39 meters. The south pole is near the center of the unlit portion on the left. …

We argue that Dactyl originated during the breakup of the Koronis parent body, and that satellites could be common around other asteroids (particularly members of asteroid families).

243 Ida is an asteroid in the Koronis family of the asteroid belt. It was discovered on 29 September 1884 by Austrian astronomer Johann Palisa at Vienna Observatory and named …

Mar 1, 1996 · Limb profiles are remarkably smooth over distances of 200–300 m. The geometric albedos of the two objects are similar (0.20 vs 0.21), as are the 0.4–1.0-μm colors. Like Ida, …

Oct 30, 2002 · This paper explores the composition of 243 Ida and Dactyl using visible and near infrared wavelength data from SSI and NIMS. This was the second asteroid encountered by …

Because Dactyl has a deeper 1-em feature than Terrain B, we would expect Dactyl to have a higher albedo than does Terrain B, whereas the opposite is the case (0.21 compared to 0.22).

Jan 1, 1996 · Galileo imaging observations over phase angles 19.5?? to 109.8?? are combined with near-opposition Earth-based data to derive the photometric properties of Ida.

Table 3 is sorted in alphanumeric order and reports the mean albedo and diameter and associated 1-sigma uncertainties for 1831 asteroids, as well as the number of sightings used to …

Abstract–We model electromagnetic scattering from varying closely packed random aggregates of spheres imitating piles of rocks on the surface of an asteroid.

It was imaged by the Galileo spacecraft on August 28, 1993; Dactyl was discovered while examining the delayed image downloads from Galileo on February 17, 1994.
