The solar system: The solar system formed around 4.6 billion years ago.When you think of the solar system you probably just think of the sun and the planets. When I think of the solar system I think of the the kuiper belt, the heliosphere, comets, the Oort cloud and the solar wind. http://universe-review.ca/ The kuiper belt is a belt of comets that are charcoal black. it is fifty times further away from the sun than Pluto is to earth. the heliosphere is the the suns magnetic field. It is surprisingly the shape of a crescent moon. There are short term and long term comets. Short term comets are comets from the kuiper belt which travel in circles returning every 300 years or less. Long term comets are mysterious and are on a plunging orbit or an infrequent orbit that is unpredictable. Theses comets are pulled in due to the gravitation pull of the sun. there is a theorized population of comets known as the Oort cloud, it is a theoretical cloud at the edge of our solar system
