In the 19th century when asteroids were first discovered, the continuum of sizes in the solar system was not understood, because many people thought of the solar system as a Sun orbited by nine planets. However, as observers' abilities to see smaller and smaller bodies in the solar system improves because of better instrumentation, and as scientists continue trying to catalog the number of large asteroidal bodies that someday might collide with the Earth, the solar system is viewed as a collection of objects with a whole continuum of sizes.
