What’s Your Address?

What's Your Address? I know where my house is on my street. I know where my street is in my town. I know where my country is on a map of the world. But sometimes, I wonder, " Where is the earth?" Imagine if you were trying to tell an alien from another planet your address! “ I live on 24 Flower Lane, Rome, Italy, Earth. ” “ Where is that?" it might ask. That's a difficult question to answer. We live in a galaxy called the" Milky Way" . It gets its name from all the stars in it. There are so many stars that it looks white, just like milk.

Our tiny planet sits near the edge of the Milky Way galaxy, with millions of other stars and planets. There are billions of galaxies too! Maybe one day, we will include our planet in our addresses!
