  The solar system   The Solar System is located in the Milky Way, a barred spiral galaxy with a diameter of about 100,000 light-years containing more than 100 billion stars The Sun resides in one of the Milky Way's outer spiral arms, known as the Orion-Cygnus Arm or Local Spur. The Solar System is the system where all planets are attached to each other, other moons and the Sun, all bound by gravity, either directly or indirectly.  It consists of a star; the Sun, the planets; a total of nine, dwarf planets; such as Pluto, moons and millions of asteroids, comets and meteoroids. The Solar System also contains smaller objects. The asteroid belt, which lies between the orbits of Mars and Jupiter, mostly contains objects composed, like the terrestrial planets, of rock and metal. Beyond Neptune's orbit lie the Kuiper belt and scattered disc, and beyond them a newly discovered population of sednoids.                            Mercury General information: This small planet spins arou

  · Big Bang The Universe we know nowadays began in a Big Bang about 14 billion years ago. The entire Universe was inside a bubble thousands of times smaller than a pinhead. Then, it suddenly exploded. The Universe was born. Time, space and was created. In less than a second, the Universe grew to a whole galaxy.  As the Universe expanded and grew it cooled and particles changed to matter and antimatter. These two types of particles destroyed each other, although some matter survived. More particles like neutrons, protons and atoms started to form when the Universe was one second old. Within the first seconds, the entire Universe’s temperature dropped 1 billion degrees Celsius and it was cold enough for the protons and neutrons to come together, forming hydrogen and helium nuclei. After 300 000 years, the Universe had cooled to about 3000 degrees.
