More (An Explorer's Guide to the Universe) By Erik Gregersen After hundreds of years of observation, theorizing, exploration, and data collection, the universe is still a mysterious place. Numerous cosmic questions remain unanswered despite the scientifi c and technological dvances made since the telescope was invented in the 1600s. But we are learning more about the cosmos all the time through intense examination of the solar system in which we live. Still, learning about the outer solar system has proved to be diffi cult, to say the least. What is known about the farthest reaches of our solar system is discussed, at great length and in fi ne detail, in this book. Scientists have launched many spacecraft into orbit. anned spacecraft have traveled as far as the moon. Unmanned probes have approached most of the planets and even landed on Mars. These probes tell scientists more about the solar system than we could ever learn with telescopes alone. In 1977, the Voyager 1 probe was sent into space for the purpose of exploring Jupiter and Saturn. Other probes were sent in the ears that followed. It took decades for these probes to reach the most distant planets and send back data about them. Presently, Voyager 1 is the farthest manmade object from Earth; it is approaching the edge of the known solar system, and scientists hope it will gain new information about the mystifying region known as the Kuiper Belt. The Voyager and other missions represent the limit of our physical reach within the cosmos. For now, we depend on the data they have collected to gain a better understanding of the outer solar system. Beyond the orbit of Mars—which represents the planetary boundary between the inner and outer solar system—is a ring of asteroids orbiting the Sun. The asteroid belt contains rocky objects left over from the formation f the solar system. The asteroids range in size from hundreds of kilometers in diameter to dust-sized particles. The largest asteroid in the asteroid belt, Ceres, is considered a dwarf planet. It was the fi rst asteroid ever discovered. By 2009, more than 450,000 asteroids had been discovered. While most asteroids orbit the sun in the main belt between Mars and Jupiter, some stray closer to Earth. These are called near-Earth asteroids (NEAs). Most NEAs are still far from Earth, but some actually cross Earth’s orbit, making them potentially deadly to life on Earth. Smaller-sized asteroids are often called meteoroids. This term is also often reserved for asteroids that collide with...... And one more wonderful book HERE!!!!
