Minor Planets: The Discovery of Minor Satellites
Science, 1979The recent confirmation of the discovery of a satellite of the minor planet 532 Herculina indicates that other similar anomalous sightings are probably also due to satellites, which must therefore be numerous and commonplace. There are now 23 candidate satellites for eight minor planets, and no one of these minor planets occulting a star has failed to ...

A hypothesis based on the accretion model of planet formation is proposed which can explain why minor planets could not grow into full-sized planets. Temperature and impact-velocity conditions for bouncing, accumulation, and fragmentation of planetesimals are evaluated for silicate and iron planetesimals at the heliocentric distances of Mercury, Venus,

Annual Review of Earth and Planetary Sciences, 2006
A review of observations and theories regarding binary asteroids and binary trans-Neptunian objects [collectively, binary minor planets (BMPs)] is presented. To date, these objects have been discovered using a combination of direct imaging, lightcurve analysis, and radar.

The Distant Minor Planets include the cis-Neptunian objects, and the trans-Neptunian objects (TNOs). The TNOs include Kuiper Belt Objects (KBOs), Scattered Disc Objects (SDOs), Detached Objects, and Oort Cloud Objects (OCOs).

Vesta, the third-largest known asteroid in our solar system, is the only asteroid that can be seen with the naked eye. Vesta is smaller than Ceres and Pallas, the first- and second-largest asteroids, respectively, but its reflective surface allows it to be seen occasionally, without the aid of a telescope, in the nighttime sky.

In order to understand the composition of asteroids, a planetary scientist has to be part detective. Undoubtedly, indirect clues, such as remote observations, are essential to solving the case of the asteroid’s composition. A spectrographic analysis of the light reflected from the asteroid’s surface, or even the changes in reflection as the asteroid ...
