How far are the stars from us?

How far are the stars from us? Reading notes are as follows:

Do you know how far the stars are from us? Last week, I read the book How Far Are the Stars from Us, which talked about a lot of astronomical knowledge, and I learned a lot through reading. I know many stars and constellations that I didn't know before. The new stars are: eros, Mercury, Venus, Mars, Jupiter, Saturn, Uranus and Neptune.

The book says that there are millions of stars in the cluster of the Milky Way galaxy, and they form a team, just like the police are divided into several teams. Some stars are far away from us and some are close to us. The brighter the star's light looks, the closer it is to us, the darker the star's light looks and the farther it is from us. The farthest galaxy is more than10 billion light years away.

The moon, the first stop for human beings to fly out of the earth and step into space, is the only planet where human beings have left footprints outside the earth so far. The moon seems to be an immortal "sky lamp". A poem named "Streets in the Sky" in the book is beautifully written, which seems to bring us into the artistic conception of beautiful starry sky.

After reading this book, I learned something, but I still don't understand a lot of knowledge in the book. I don't know what Pythagorean theorem is, and I don't know the distance of "light years", but I will definitely understand it through study in the future. I am very happy to be friends with this book. In the future, I will learn more about astronomy.
