Oxford Astronomy, S. & J. Mitton, Oxford University Press (2003)
A popular text with pretty pictures. It gives a guided tour of space, in particular the Solar System. Illustrated orbits of planets and comets provide a useful introduction to the different scales.

The Lighter Side of Gravity, J.V. Narlikar, Cambridge University Press (1996)
A lucid explanation of gravity on a non-technical level, ranging from planets to black holes. Even experts can benefit by reading this delightful book, with its original ways of looking at the subject of gravitation from Newton to Einstein.
The Art of Computational Science, P. Hut & J. Makino (2004), artscicom.org, This is a series of books published on the web (a 10 year project) written as a dialogue between two young people.
