Billy’s Wonderful Galaxy Tour is a Children’s Book that is designed for 5-7 year old children to inspire them in the cosmos and educated them about the eight planets of the solar system. To achieve the goal, this book tells a simple but interesting story and communicates with children by using an engaging style of illustration. To gain children’s interest, all the planet characters are illustrated in an anthropomorphic style and their respective clothing and colors are based on their own characteristics and facts. This in turn will help children learn and memorize the facts about astronomy.
