Comets. -More than 3000 comets have been discovered. -May take hundreds or even 1000s of years to orbit the sun. -240 BC was the earliest sighting of a comet. Halley's Comet is arguably the most famous comet. It is a "periodic" comet and returns to Earth's vicinity about every 75 years, making it possible for a human to see it twice in his or her lifetime. The last time it was here was in 1986, and it is projected to return in 2061.. By Trevor Todd and Michael Tran. What are asteroids made. . of?.

Comets, like asteroids are small celestial bodies that orbit the sun. However, unlike asteroids comets are made mostly of frozen ammonia, methane or water, and contain only small amounts of rocky material.. While we worry over the depletion of the earth\'s natural resources, the pollution of our planet, and the challenges presented by the earth\'s growing population, billions of dollars worth of metals, fuels, and life-sustaining substances await us in nearby space. In this visionary book, noted planetary scientist John S. Lewis explains how we can mine these precious metals from the asteroids, comets, and planets in our own solar system for use in space construction projects. And this is just one of the possibilities. Join John S. Lewis as he contemplates milking the moons of Mars for water and hollowing out asteroids for space-bound homesteaders—all while demonstrating the economic and technical feasibility of plans that were once considered pure fiction. .. They have also been called . planetoids. , especially the larger ones. Formation.
