The parts of the solar system that are most accessible from Earth (the Moon, the near-Earth asteroids, and Mars and its moons) are rich in materials of great potential value to humanity. Immediate uses of these resources to manufacture propellants, structural metals, refractories, life-support fluids and glass can support future large-scale space activities. In the longterm, non-terrestrial sources of rare materials and energy may be of great importance here on Earth.

The book presents in a readable, yet soundly scientific, language a popular account of eclipses of the Sun and Moon, and very briefly of certain kindred astronomical phenomena similar to those which operate in connection with eclipses.
A trans-Neptunian object is any minor planet in the Solar System that orbits the Sun at a greater average distance (semi-major axis) than Neptune. The Kuiper belt, scattered disk, and Oort cloud are conventional divisions of this volume of space.
The Solar System comprises the Sun and its planetary system, as well as a number of dwarf planets, satellites, and other objects that orbit the Sun. It formed 4.6 billion years ago from the gravitational collapse of a giant molecular cloud.
