Question 3

What is the biggest planet in the Solar System?

Accepted Answer

The biggest planet is Jupiter. It's so big that all the other planets could fit inside it!

Question 4

What is the smallest planet in the Solar System?

Accepted Answer

The smallest planet is Mercury. It's closest to the Sun and is a bit bigger than our Moon.

Question 5

How many planets are in the Solar System?

Accepted Answer

There are eight planets in the Solar System. They are Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, and Neptune.

Question 6

Why is Earth special?

Accepted Answer

Earth is special because it's the only planet we know of where people, animals, and plants live. It has water and air that we need to stay alive.

Question 7

What is a moon?

Accepted Answer

A moon is a natural object that goes around a planet. Some planets, like Earth, have one moon, and others have many. Jupiter has the most, with over 70 moons!

Question 8

What are asteroids?

Accepted Answer

Asteroids are rocky objects that are much smaller than planets. Most of them orbit the Sun in a region called the asteroid belt, which is between Mars and Jupiter.

Question 9

What are comets?

Accepted Answer

Comets are icy objects that travel around the Sun. When they get close to the Sun, they heat up and release gas and dust, forming a bright tail that we can see in the sky.

Question 10

What is the Sun made of?

Accepted Answer

The Sun is made mostly of hot gases called hydrogen and helium. It gives off light and heat, which makes life on Earth possible.

Question 11

How do the planets stay in orbit around the Sun?

Accepted Answer

The planets are held in orbit by the Sun's gravity. Gravity is a force that pulls objects toward each other, like how you stay on the ground instead of floating into the air.

Question 12

Can people live on other planets?

Accepted Answer

Right now, people can't live on other planets. They are either too hot, too cold, or don't have the air and water we need, but scientists are exploring ways to make it possible in the future.

Question 13

What is a space probe?

Accepted Answer

A space probe is a robot spacecraft sent to explore space. It takes pictures and sends back information about different parts of the Solar System.

Question 14

Have humans visited any planets?

Accepted Answer

Humans have not yet visited other planets. But astronauts have gone to the Moon, and robots and probes have visited other planets in our Solar System.

Question 15

What is the Kuiper Belt?

Accepted Answer

The Kuiper Belt is a region of space beyond Neptune filled with small icy objects. It includes Pluto, which was once considered a planet.

Question 16

Why was Pluto reclassified as a 'dwarf planet'?

Accepted Answer

Pluto was reclassified because it's much smaller compared to the other planets and shares its space with similar icy objects in the Kuiper Belt.

Question 17

What is the difference between a star and a planet?

Accepted Answer

A star, like the Sun, is made of hot gases and shines brightly in the sky. A planet is a large, round object that orbits a star and doesn't produce its own light.

Question 18

How do we explore the Solar System?

Accepted Answer

We explore the Solar System with telescopes, satellites, space probes, and manned space missions. These tools help us learn more without leaving Earth.

Question 19

What protects Earth from harmful space objects?

Accepted Answer

Earth is protected by its atmosphere, which burns up most small objects that come towards us from space. This is why we often see shooting stars at night.

Question 20

Why do we study the Solar System?

Accepted Answer

We study the Solar System to understand how it works and learn about our place in the universe. It also helps us discover if there are other planets that could support life.
