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

Question 3

What makes the Sun important?

Accepted Answer

The Sun is a big, hot ball of gas that makes light and heat for us. It helps plants grow and keeps the planets in orbit with its strong gravity.

Question 4

Why is Earth special?

Accepted Answer

Earth is special because it is just the right distance from the Sun to have liquid water, which is important for life. It also has air to breathe and a protective atmosphere.

Question 5

What are asteroids?

Accepted Answer

Asteroids are big rocks that orbit the Sun. Most of them are found in the 'asteroid belt' between Mars and Jupiter.

Question 6

What is a comet?

Accepted Answer

A comet is a space object made of ice, dust, and rocks. It makes a glowing cloud and tail when it gets close to the Sun.

Question 7

How do moons stay close to planets?

Accepted Answer

Moons stay close to planets because of gravity, which is like an invisible force. Gravity keeps the moons spinning around their planets.

Question 8

What is the largest planet in the Solar System?

Accepted Answer

The largest planet in the Solar System is Jupiter. It's a giant gas planet and is much bigger than all the other planets.

Question 9

Why can't we live on Mars right now?

Accepted Answer

Mars is very cold, doesn't have enough air we can breathe, and has no liquid water on its surface. Scientists are studying it to see if humans might live there one day.

Question 10

What are rings around planets made of?

Accepted Answer

Rings around planets are made of ice, dust, and small rocks. Saturn is the planet with the most famous and visible rings.

Question 11

How far away is the Sun from Earth?

Accepted Answer

The Sun is very far from Earth, about 93 million miles away. That's so far that light from the Sun takes about 8 minutes to reach us.

Question 12

What do we call the path planets take around the Sun?

Accepted Answer

The path that planets take around the Sun is called an orbit. An orbit is usually a slightly 'squished' circular shape.

Earth has one moon. It's the big, round, glowing object we see in the night sky.

Question 14

What is a dwarf planet?

Accepted Answer

A dwarf planet is like a smaller version of a planet. They orbit the Sun like regular planets, but they're not big enough to clear other space rocks out of their path.

Question 15

Is there a planet made entirely of gases?

Accepted Answer

Yes, the giant planets like Jupiter and Saturn are mostly made of gases. They don't have a solid surface like Earth.

Question 16

Why is Pluto not a regular planet anymore?

Accepted Answer

Pluto is considered a 'dwarf planet' because it is smaller and doesn't clear other objects out of its orbit. It used to be the ninth planet, but scientists changed its status in 2006.

Question 17

What keeps the planets in orbit around the Sun?

Accepted Answer

Gravity, the same force that keeps us on the ground, holds the planets in orbit around the Sun. It's like an invisible tether pulling them towards the Sun.

Question 18

Which planet is known for its beautiful rings?

Accepted Answer

Saturn is known for its beautiful rings. People can even see some of them with a small telescope.

Question 19

Can we see other planets from Earth?

Accepted Answer

Yes, we can see some planets from Earth with our eyes, like Venus and Mars. They look like bright stars in the sky.

Question 20

Is there life anywhere else in the Solar System?

Accepted Answer

We don’t know yet if there is life elsewhere in the Solar System. Scientists are looking for signs of life on places like Mars and some of Jupiter's and Saturn's moons.
