 objects left over from the formation of the solar system more than 4 billion years ago. 

 several feet to hundreds of miles across, these rocky bodies are too small to be considered planets. 

undiscovered asteroids were detected using a new algorithm called Tracklet-less Heliocentric Orbit Recovery (THOR)

 is crucial to understanding our solar system, enabling development of space and protecting earth from impacts

 ADAM, any telescope with an archive can now become an asteroid search telescope," said Lu, former NASA astronaut.
