Este libro sobre el Sol comenta su importancia para la Tierra y su función en el universo.
Our closest solar system is about 10 light years away. It has two main types of planets. Some are rocky and small, like planet Earth, while others are huge balls of gas, like Jupiter. Learn about how astronomers once thought our solar system was the one and only, to how they have now discovered hundreds of stars with planets orbiting them, which means there could be billions of solar systems in outer space! Just maybe, these alien worlds could host life, like our own amazing planet. This book allows students to use observations of the Sun, moon, and stars to describe patterns that can be predicted.
Five and counting! So far, astronomers have discovered five dwarf planets in our solar system. Pluto, which was once thought of as the ninth planet, is today classified as a dwarf planet. This book looks at the current dwarf planets, characteristics, size, and orbital patterns, as well as the three rules scientists follow to characterize these tiny, round space objects. Every day new discoveries are being made. Who knows how many dwarf planets we will find in the future! This book will allow students to understand that patterns in the natural world can be observed, used to describe phenomena, and used as evidence.
