Did you know that we live in a galaxy filled with planets? Our galaxy is called the Milky Way, and our solar system is just a tiny part of it. There are eight planets in our solar system. Mercury is the closest to the Sun, and it's so hot, metal can melt there. Venus, the second planet, is the hottest, even hotter than Mercury! Earth is the third planet, and it's just right for us because it has water and air. Mars, the red planet, is next. After Mars, there's the giant Jupiter, with its big red spot. Saturn is famous for its beautiful rings. Uranus and Neptune are the furthest planets, and they're very cold! Pluto, once considered the ninth planet, is now called a 'dwarf planet'. Among all these planets, Earth is the most special, because it's the only one we know that supports life. Let's take care of our unique home!
