Small Bodies of the Solar System

1999
In addition to the Sun, Moon and major planets, the lesser members of the Solar System can also be participants in transient phenomena of interest to the astronomical observer. Meteor activity, produced by small particles – meteoroids – usually of cometary origin, has already been discussed (Chapter 2).

Small Bodies of the Solar System

1995
Neptune had been discovered in 1846 because of irregularities in the orbit of Uranus, but, in many ways, its discovery was fortunate, as it was much closer to Uranus than either Le Verrier or Adams had assumed. Le Verrier was not convinced that Neptune was the limit of the solar system, and said so to Galle on 1st October 1846, but he recognised that ...

Space Weathering of Small Solar System Bodies

Earth, Moon, and Planets, 2009
Micrometeorite bombardment and irradiation by solar wind and cosmic ions cause variations in the optical properties of the small Solar System bodies surface materials. These space weathering processes are reasonably well understood for the Moon and S-type asteroids.

Exploration of Small Solar System Bodies

2016
So far we have learnt a lot about the different types of Small Solar System Bodies and dwarf planets. Yet, the question remains. How do we get all the information from these small, distant bodies? These small objects are very difficult to observe. Using optical telescopes, even the largest ones we currently have on Earth, it is hardly possible to see ...

The Small Bodies of the Solar System

2001
Comets have been seen since time immemorialbut asteroids were only discovered at the begining of the nineteenth century while the first members of the family of bodies that orbit in the region beyond Neptune were only discovered within the last ten years.

Populations of Small Solar System Bodies

2019
Asteroids are objects that are mainly composed of rocky and metallic material, are generally accepted to be debris left over from the formation of the solar system. The exact composition varies with the asteroid, but in addition to rocky material, asteroids may contain metals and volatiles including organic material.

Water on Small Solar System Bodies

2011
When examining the outer parts of the solar system water becomes more and more abundant. The water reservoir on the Erath and other terrestrial planets might have been supplied by the impact of these objects in the heavy bombardment phase of the early solar system evolution.

Small (and Not So Small) Solar System Bodies

2010
This chapter will cover the somewhat confusing terminology surrounding: How planets, dwarf planets, and asteroids are so defined. The meaning of the myriad of numbers and names used to designate asteroids. The quantities used to describe the orbit of an asteroid around the Sun – its orbital elements.

The Science of Small Solar System Bodies

2019
On February 15, 2013, the city of Chelyabinsk, Russia was struck by a small rocky body about 20 m in diameter. The body exploded at a height of about 30 km above the ground. The resulting shockwave broke windows in over 7000 buildings and injured more than 1500 people.

Dynamics of small bodies in the solar system

The European Physical Journal Special Topics, 2010
In this chapter we review key results on the dynamics of small solar-system bodies, such as asteroids and comets. We begin by presenting the main populations of small bodies in the solar system, in terms of their orbital characteristics. We define the different types of resonant interactions for small bodies, relating them to the orbital structure of ...
