The asteroids are a series of small, heavenly bodies whose orbits fall mainly between those of Mars and Jupiter. The largest asteroid is 620 miles in diameter, the smallest, less than one mile. The use of the asteroids brings an influx of new symbols, and the addition of new symbols means the number of ideas which may be communicated is increased. It is as if you were working with a language which contained a vocabulary of ten words. You could create many more meanings than ten by combining these words in different ways. But consider how much richer the possible communication becomes if you suddenly have more than twice as many words to play with.
