    The planets, millions of asteroids, tens of thousands of comets, distant icy worlds, and countless other bits and pieces of material orbit the Sun. A group of such co-orbiting objects is called the Taurid complex or swarm. It consists of Comet 2P/Enke, a number of near Earth asteroids, and the meteor stream which produces the Taurid meteor shower every October and November.

    When the Japanese spacecraft Hayabusa [Hi ya Boo sa] visited the near Earth asteroid Itokawa in 2005 it found this 2000 foot by 800 foot elliptical world to have a variety of surface features. Instead of being a solid object like some asteroids, Itokawa is a rubble pile of boulders and pebbles held together by it's tiny gravity. The total volume of pebbles seems to be comparable to the volume of large rocks and boulders which make up Itokawa , however, the depths of the pebbles or their concentration in the center remains unknown. Given this uncertainty, this asteroid appears to be made up of a million times more small particles than larger ones.

    Astronomers have discovered some 1.4 million asteroids. Approximately 35,000 of these space rocks come near Earth. Less than 40 of them are classified as being Atira asteroids whose orbits lie entirely within the Earth’s orbit about the Sun. Only one of these, asteroid number 594913 named 'Ayló'chaxnim (eye-LAW-chax-nim ) has an orbit which is entirely within the orbit of the planet Venus.
