The largest planet in our solar system is Jupiter. It's so big that all the other planets could fit inside it!

Question 10

What is the smallest planet in our solar system?

Accepted Answer

The smallest planet is Mercury. It's the closest planet to the Sun and is about the size of Earth's moon.

Question 11

What makes Earth special?

Accepted Answer

Earth is special because it is the only planet we know of that has life. It has water, air, and the perfect temperature for living things.

Question 12

Why do planets orbit the Sun?

Accepted Answer

Planets orbit the Sun because of gravity. The Sun's gravity pulls the planets towards it, making them travel in circles or ellipses around it.

Question 13

What is gravity?

Accepted Answer

Gravity is a force that pulls objects towards each other. It keeps us on the ground and makes the planets orbit the Sun.

Question 14

Why does the Sun shine?

Accepted Answer

The Sun shines because it is very hot and burns gases, mostly hydrogen, in a process called nuclear fusion. This process releases a lot of energy that we see as light and feel as heat.

Question 15

Accepted Answer

Yes, but not for a very, very long time. The Sun has enough fuel to shine for about 5 billion more years.

Question 16

Why does it get colder as you move away from the Sun?

It gets colder as you move away from the Sun because you're moving farther from its heat and light. Just like a campfire, the closer you are, the warmer you feel.

Question 17

What is the asteroid belt?

Accepted Answer

The asteroid belt is a region in space between Mars and Jupiter where many asteroids orbit the Sun. It's like a rocky ring around the Sun.

Question 18

Can we see planets without a telescope?

Accepted Answer

Yes, you can see some planets without a telescope! At night, you might see planets like Venus, Mars, Jupiter, and Saturn shining in the sky like stars.

Question 19

What is a solar system model?

Accepted Answer

A solar system model is a way to show how the planets and other objects orbit the Sun. It helps us understand where everything is and how they move in space.

Question 20

How do we learn about the solar system?

Accepted Answer

We learn about the solar system using telescopes, spacecraft, and space probes. Scientists study these to understand more about space and the objects in it.
