Voyage to the Planets essays The solar system holds many scientific mysteries. It is a universe full of wonder. What exactly is it? How was it created? When? Why? These are just a few of the many questions we ask ourselves all the time. In the following, the mysteries of this solar system, how it was created, its planets, the history of space travel, and the other phenomenas will be uncovered. There are many theories surrounding how the universe came about. The Big Bang Theory is the most sought out for explanation. It suggests everything started by a huge explosion about eight to ten billion years ago. The planets were formed from dust material and debris four and a half million years ago after the explosion of a super nova. The death of this star led to birth of a new star, the center of the universe, we know as the Sun. The remaining debris from the blast was then sucked in as the gravity drove up. The material then came together resulting into the four inner four planets, as of the 100 they originally were, the rest became the Oort Cloud, the Kuiper Belt, and asteroids. Every 52 years, the Aztecs made a sacrifice for the Sun, believing if they didnt, it would die. The Aztecs were known as the people of the sun. The sun is very important to our survival. Without the Sun, there would be no life on Earth. The sun provides light, heat, and other energy to Earth. The Sun is a huge, glowing ball at the center of our solar system. It is not a first generation star. Nine planets and their moons, tens of thousands of asteroids, and trillions of comets revolve around the sun. Every five billions years our Sun orbits the galaxy. The sun is made up entirely of gas, hydrogen and helium. The part of the Sun that we see has a temperature of about 5500 C (10,000 F). The temperature of the solar surface is about 5800 K. Temperatures in the Sun's core reach over 15 million K. Next are the inner planets: M...
