Collective Resonant Phenomena On Small Bodies In The Solar System

Celestial Mechanics and Dynamical Astronomy, 1992
For both asteroids and meteor streams, and also for comets, resonances playa major role for their orbital evolutions but on different time scales. For asteroids both mean motion resonances and secular resonances not only structure the phase space of regular orbits but are mainly at the origin for the inherent chaos of planet crosser objects.

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.

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 ...

Phobos and other small bodies of the solar system

Planetary and Space Science, 1991
Abstract Phobos is the first asteroid-like body to be observed at close range: during the Viking mission, several close fly-bys made possible extensive mapping of its surface at resolutions down to a few m. During the Phobos mission, two encounters at a distance of about 200 km were performed before the premature termination of the mission, on March ...

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.

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.

Comets, Small Bodies, and Problems of the Solar System

Publications of the Astronomical Society of the Pacific, 1962
Lately, new and important data concerning the nature and motions of the different types of small bodies of the solar system have been obtained. These lead to quite definite conclusions as to the evolution and origin of these bodies. The number of comets. Over the entire period of recorded history about 2000 comet appearances have been noted. Out of 813

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.
