📖 English Story

Hello, I am Hana, and I want to be an astronaut someday. Last night, I read a book about space before I went to sleep. Then I had an amazing dream. I was flying through space in a shiny silver rocket!

First, I saw the Sun, which is a giant star made of hot gas. It was so hot that I had to keep my rocket far away. Eight planets travel around the Sun. Each planet moves on its own path. This path is called an orbit.

Next, I visited the four planets closest to the Sun: Mercury, Venus, Earth, and Mars. They are small, rocky planets with hard ground. Mars looked red because it is covered in rusty dust. Earth looked blue and green, and it felt like home.

Then I flew far out to the two biggest planets. Jupiter and Saturn are huge balls of gas with no solid ground to stand on. Jupiter is the biggest planet. More than a thousand Earths could fit inside it. Saturn has wide, bright rings made of ice and rock.

Last, I reached Uranus and Neptune, the two planets farthest from the Sun. They are called ice giants because they are very cold and icy. Uranus spins on its side, and Neptune has the strongest winds of all.

Suddenly, my alarm clock rang, and I woke up. It was only a dream, but I learned so much about our solar system. One day, I hope to ride a real rocket into space!

🔬 오늘의 상식

태양계는 스스로 빛을 내는 별인 태양과 그 주위를 도는 8개의 행성 등으로 이루어져 있어요. 행성은 태양에서 가까운 순서대로 수성, 금성, 지구, 화성, 목성, 토성, 천왕성, 해왕성이에요. 수성, 금성, 지구, 화성은 단단한 암석으로 되어 있고, 목성과 토성은 거대한 기체 행성, 천왕성과 해왕성은 아주 차가운 얼음 행성이에요. 예전에는 명왕성도 행성이라고 했지만, 2006년부터는 '왜행성'으로 분류해요.
