The topic of this book is to tell how to find faraway planets and to explain what they are and how they work. The information about the topic that is shared is how to find planets that are out of our solar system and what they could be like, for example the book said that H2-b is a planet out of our solar system, and that H2-b is hot because it orbits close to its sun. What I already knew about this topic is that there are lots of planets, and the planets are all different.
This planet is the free floating planet closest to Earth.
One fact I learned from this book is that stars can be pulled by their planets gravity.
Another fact I learned from this book is that some gas giants in other galaxies actually lose gas from their atmospheres as they fly through space.
The final fact that I am going to share with you that I learned is that in comparison planets are pea's and stars are basketballs
Keep in mind that the planet in this picture is HUGE compared to even Jupiter.
A Graphic Used in the Text
A graphic used in the text is a picture of planet HD-2b, it shows HD- 2b leaking gas. This graphic supported the text by showing how planets could leak gas out of their atmosphere. This graphic is used on page 23.
What is the author's purpose in writing this book?
What the authors purpose in writing this book is to inform, meaning he tells me information about a subject.I know because the authors purpose in writing this book was to inform how to find exoplanets, planets out of our solar system, and what exoplanets could be like if you where on them. The book tells how to find exoplanets by giving a example saying, "A good clue to a exoplanet is a star that wobbles." This is a good clue because a star wobbles when it is being pulled on by its own planet"s gravity. An example of this is when someone is walking their dogs and they pull the dogs, but the dogs pull them too. Another purpose of the author is to say what exoplanets could be like if you were on them. The book tells what exoplanets could be like if you were on them by giving examples, I will tell you some of those examples. One example taken directly from the book is, "That there could be a world full of deadly gases, 2,000 degrees Fahrenheit regularly, where a year is three and a half days long." Another example is that there could be a exoplanet that has no oxygen, poisonous chemicals in the air, and reeks badly. These are my reasons why the author wrote this book.
