False! Saturn's beautiful rings are not made of clouds. They are made of billions of tiny pieces of ice and rock orbiting the planet. Some pieces are as small as grains of sand, while others are bigger than a house!
Jupiter is the biggest planet in our solar system.
Yep, that's right! Jupiter is so big that all the other planets in our solar system could fit inside it! It's a gas giant, which means it's mostly made of gas, not solid ground like Earth.
The Moon has mountains and valleys just like Earth.
Yes, that's true! The Moon's surface is full of mountains, valleys, and big holes called craters. These were made when rocks from space crashed into the Moon a very long time ago.
All planets in our solar system are perfectly round like balls.
False! All parts of the Moon get sunlight. The side we don't see from Earth is called the 'far side,' but it gets lit up by the sun just like the front, just at different times during the month.
Astronauts can get a little taller when they are in space.
Yes, it's true! Without Earth's gravity, your spine stretches out a bit, so astronauts can become up to a few centimeters taller. But when they come back to Earth, they return to their normal height!
A day on the planet Venus is longer than a year on Venus.
That's true! Venus spins so incredibly slowly around its own middle that one single day there takes longer than it takes for Venus to go all the way around the Sun!
No, that's not right! Sound waves need something to travel through, like air or water. Since space is almost a perfect vacuum, there's nothing for sound to travel through. That's why space is completely silent. Imagine how quiet it would be outside your spaceship!
