This book is dedicated to math teachers trying to inspire young minds with mathematical reasoning.

Hi there! I'm Luna, child astronaut, and I love space! When I'm not traveling through space I spend most nights at home looking through my telescope. I love seeing all of those sparkling stars and the moon up close, I can even find a few planets every now and again. Nothing seems to really stay in the same place for very long. Do you want to come look with me? I'll teach you everything I know!






Our Solar System and everything in it is so massive, but some how everything looks so small from here. The sun is the center of our Solar system, but we can not look at that because it would hurt our eyes.

The sun is actually a star. It is the closest star to Earth which is why it seems so big, even though it is considered a medium sized star.
It is made of a very hot gas, and if the Earth was any closer life would not be possible!

Everything in space is constantly moving. There are two main types of movements that occur in space: rotation and revolution. Revolution is when one object circles around a different object. Rotation is when one object spins around on its own axis.

The sun revolves around the center of the Milky Way Galaxy. The Earth, and all of our other planets, revolve around the sun. Even the moon revolves around the Earth. While the Earth, moons, and other planets are revolving they rotate on their axis's at the same time. With all of this spinning you would think we would be dizzy all the time!


Let's look at the moon! I love the moon. My name, Luna, is the Latin word for moon. Have you noticed that the moon takes on different shapes throughout the month? These are called the phases of the moon, and there are eight of them.



The phases of the moon all depends on its relationship between the Earth and the Sun.
As the moon revolves around the Earth, we see the bright parts at different angles, which is what creates those different shapes.


As we speak the moon is revolving around us and rotating on it's axis. The moon orbits, or revolves around, the Earth once about every 27.3 days. It also rotates once around its axis every 27 days. Since the moon has a synchronous rotation it appears to stand still.


Let's travel to the moon so we can get a better look at the Earth! Don't worry, I might not be old enough to drive a car, but I've got this rocket ship under control.




Almost there!

Well we made it! Look, there's our home planet. It looks so small from 238,900 miles away.


Just like the moon, the Earth is always moving. It takes about 365.25 days to revolve around the sun. Does that number sound familiar? We have 365 days in a calendar year to help keep track of time.


While the Earth is orbiting the sun, it is also rotating on it's axis. One rotation is the length of one day. Can you guess how many hours it takes to rotate?
