Friday’s Factoid 9 (by Titus and Joel)

The Earth is the most special planet in the whole solar system and the only one people can live on. It has just the right amount of everything like sunlight, gravity, atmosphere, tilt and spin so that people won’t freeze or burn up or starve or fall off. I am glad we live here but I would like to visit another planet too (Joel,7).

The Earth is in the Milky Way Galaxy. The Milky Way is a Spiral Galaxy and our solar system is not in the middle. It is more on the edge. The Milky Way is over 100,000 light years across. A light year is almost 6 trillion miles. There are no pictures of the whole Milky Way because no one has been out of it. Once, the Voyager took a picture of the Earth from 4 billion miles away and it was just a little dot in the middle of a sunbeam (Titus,8).
