The Smallest Planets In The Solar System – 3D Solar System For Kids

Welcome to our exciting journey through the solar system! Today, we’re going to learn about some amazing planets. Are you ready to explore?

Exploring Earth

Let’s start with our home, planet Earth. Did you know Earth is the only planet we know of that has life? That’s why it’s so important to take care of our environment. Earth travels around the Sun, and it takes 365 days to go all the way around. This journey is called a revolution, and it gives us different seasons. Earth also spins around itself, which takes 24 hours. This spinning is called rotation and it makes day and night happen.

Long ago, people thought Earth was flat, but now we know it’s shaped like a ball, or a sphere. About 70% of Earth’s surface is covered in water. Isn’t that cool?

Visiting Venus

Next, let’s visit Venus, the second planet from the Sun. Venus is almost the same size as Earth, but it’s much hotter because it has a thick atmosphere that traps heat. It used to have an ocean, but now it’s gone. Venus is named after the Roman goddess of love and beauty because it shines so brightly in the sky. You can see it from Earth at sunrise and sunset, which is why it’s called the morning star or evening star.

On Venus, there are lots of volcanoes and rocks called basaltic rocks. Did you know Venus spins in the opposite direction of most planets? More than 40 spaceships have visited Venus to learn more about it!

Exploring Mars

Now, let’s head to Mars, the fourth planet from the Sun. Mars is known as the red planet because of its color. It has seasons, volcanoes, and mountains just like Earth, but it’s smaller and doesn’t have water on the surface. Mars has big wind and sand storms, so watch out!

Mars has two moons named Phobos and Deimos. One of its volcanoes, Olympus Mons, is the biggest in the solar system! Did you know the first person to see Mars through a telescope was Galileo in 1610?

Discovering Mercury

Finally, let’s visit Mercury, the closest planet to the Sun. Even though it’s close to the Sun, it’s not the hottest planet because it has a thin atmosphere. Mercury is the smallest planet in our solar system and has lots of craters from meteorites. It used to be covered in a mineral called graphite, which is used in pencils.

Mercury is the fastest planet to travel around the Sun, taking only 88 Earth days to complete one trip. Its gravity is weaker than Earth’s, so things weigh less there.

Wow, what an adventure! We’ve learned so much about these fascinating planets. Keep exploring and discovering new things about our amazing solar system!

  1. What do you think it would be like to live on a planet like Venus or Mars? How would it be different from living on Earth?
  2. If you could visit any of the planets we talked about, which one would you choose and why? What would you want to see or do there?
  3. Earth is the only planet we know of that has life. Why do you think it’s important to take care of our planet? Can you think of some ways we can help protect it?
  1. Planet Rotation Experiment: Use a flashlight and a small ball to demonstrate how Earth rotates and revolves around the Sun. Have one child hold the flashlight to represent the Sun, while another child slowly spins the ball to show Earth’s rotation. Then, walk the ball around the flashlight to demonstrate Earth’s revolution. Discuss how this causes day and night and the changing seasons.

  2. Create Your Own Planet: Using clay or playdough, let the children create their own planet. Encourage them to think about what their planet would look like, what kind of atmosphere it might have, and if it would have any special features like volcanoes or oceans. Ask them to name their planet and share one interesting fact about it with the class.

  3. Observation Journal: Encourage the children to keep a journal for a week where they note down the position of Venus in the sky at sunset or sunrise. Ask them to draw what they see and write a sentence about how the planet’s position changes each day. Discuss their observations and relate them to Venus being called the morning or evening star.

Here’s a sanitized version of the YouTube transcript:

[Music] You are looking at the solar system. We are going to take a deeper look at planet Earth. Do you want to join us?

The Earth is the only known planet to have life. Hold on tight, here we go! Now we’re on Earth, a planet full of life. That is why it is so important for us to protect and take care of the environment.

Hello, Earthling! I am going to tell you some interesting facts about the planet where you Earthlings come from. Like the other planets, the Earth rotates around the Sun, and it takes 365 days to complete a full orbit. We call this a complete revolution. Thanks to this revolution, we have different seasons throughout the year, and days and nights have different lengths.

At the same time, the Earth rotates around itself, and it takes 24 hours to complete a full trip. This movement is called rotation. The Earth’s rotation is responsible for the change between day and night and for the rising and falling of temperatures.

Did you know that many years ago, people thought that the Earth was flat? Now you can see the Earth has the shape of a sphere. Approximately 70% of the Earth’s surface is covered in water. Did you like this quick trip around the Earth? Now it’s time to collect all the information you have learned. Have a good trip!

[Music] You are looking at the solar system. We are going to take a look at Venus. Do you want to come?

It is the second planet in the solar system and is almost the same size as Earth. Grab on, we’re headed that way! Now we’re on Venus, the hottest planet in the solar system. It has a really dense atmosphere causing a greenhouse effect that traps the Sun’s rays. That is why it is so hot.

Hello, Earthling! Welcome to Venus. Here, there used to be a big ocean like on Earth, and because of that, it is possible that there was life. However, the ocean disappeared for unknown reasons. I will tell you some more facts about Venus.

The name Venus comes from the Roman goddess of love and beauty, since its shine reminds us of her. Venus is also known as the morning star or evening star because from Earth, it can only be seen at sunrise and sunset. On this planet, there is a lot of volcanic activity, and we can find basaltic rocks like the ones used for construction.

Did you know that Venus’s rotation is opposite from all the other planets in the solar system? More than 40 unmanned spaceships have explored this planet. Did you like your quick trip around Venus? Now you can go back to Earth to share all that you’ve learned. Have a good trip!

[Music] You are looking at the solar system. We are going to take a look at Mars. Do you want to join?

It is the fourth planet in the solar system. Grab on, we’re headed that way! We’re now on Mars, the red planet. We call it that because of its color, but the name comes from the Roman mythological god of war. Mars is similar to Earth; it has seasons, volcanoes, and mountains, but it is smaller and it doesn’t have water. There are many wind and sand storms, so be careful and protect yourself!

Hello, Earthling! I welcome you to Mars. In the past, there was water in the depths of Mars, but it hasn’t been confirmed if there is life or not, although some of NASA’s photographs show possible signs of life. I will tell you some interesting things about it.

Due to the high volcanic activity, the mineral tridymite is formed. One of its volcanoes, Olympus Mons, is the biggest in the solar system; it is three times taller than Mount Everest. Mars has two moons, Phobos and Deimos. Phobos keeps getting closer and closer and will eventually crash into Mars.

Did you know that the first person to see Mars with a telescope was Galileo in 1610? Did you like our quick trip around Mars? Now you can go back to Earth to share what you’ve learned. Have a good trip!

[Music] You are looking at the solar system. We are going to take a look at Mercury. Do you want to come? It is the closest to the Sun. It is so close that the Sun looks three times as big from Mercury than it does from Earth. Grab on, we’re headed that way!

We are now on Mercury, the smallest planet in the solar system. Even so, it isn’t the hottest because the atmosphere is really thin and doesn’t trap the Sun’s rays. There is even ice in some of the cold and dark areas where the rays don’t reach. It is grey and has a bunch of craters due to meteorites that hit it, so be careful—they can hit you!

Hello, Earthling! Welcome to Mercury. Life has never been found here. I will be the one to tell you some interesting facts about the planet. Many years ago, it was covered in graphite, a mineral that is used to make pencil lead. Today, there are remains of this mineral.

Did you know that Mercury is the fastest rotating planet around the Sun? It rotates at 50 kilometers per second, and it only takes 88 Earth days to complete one trip. As you can see, on Mercury, there are meteorite showers that make it the planet with the most craters in the solar system. Earth’s core is so small that its gravitational force is lower than on Earth. This means that one gram on Earth is equal to 0.38 grams on Mercury.
