Comet Introduction Comets are small, fragile, irregularly shaped bodies composed of a mixture of non-volatile grains and frozen gases. They have highly elliptical orbits that bring them very close to the Sun and swing them deeply into space. http://www.solarviews.com/eng/comet.htm Visitor Rating: (Note: Turn off pop-up blocker!)

Comets Unlike the other small bodies in the solar system, comets have been known since antiquity. There are Chinese records of Comet Halley going back to at least 240 BC. The famous Bayeux Tapestry, which commemorates the Norman Conquest of England in 1066, depicts an apparition of Comet Halley. http://www.nineplanets.org/comets.html Visitor Rating: (Note: Turn off pop-up blocker!)
