The Solar System
The solar system is the space environment closest to our home planet Earth and is the most important in terms of human habitation. The solar system family includes the major planets with their satellites as well as numerous small bodies (asteroids, comets, meteoroids, and interplanetary dust). The major planets fall into two categories: terrestrial solid planets and giant gaseous-icy planets. Nearly all the satellites in the solar system belong to the giant planets, which also have systems of rings. The numerous small bodies are regarded as remnants of the solar system formation that have preserved pristine matter. The remarkable properties of the solar system dynamics involving different types of orbital and rotational resonances, migration of the small bodies, and collisional interactions with major planets throughout the solar system history have important implications for its evolution.
