Accepted Answer

Stars are big balls of gas that shine bright in the night sky. The closest star to us is the Sun, which gives us light and warmth.

Question 4

Planets are big round objects that orbit, or go around, a star. In our solar system, Earth is one of the planets that orbits the Sun.

Question 5

Question 6

What is the solar system?

Accepted Answer

The solar system is a group of planets and other objects that orbit our star, the Sun. It includes planets like Earth, Mars, and Jupiter.

Question 7

Why do stars twinkle?

Accepted Answer

Stars twinkle because their light has to pass through the Earth’s atmosphere, which is full of moving air. This makes the light wobble, so the stars look like they're twinkling.

Question 8

How do telescopes help us see space?

Accepted Answer

Telescopes act like magic eyes that help us see things far, far away in space. They gather more light than our eyes can, so we can see stars and planets more clearly.

Question 9

What is a black hole?

Accepted Answer

A black hole is a place in space with a lot of gravity, so much that nothing can escape from it, not even light. That's why it's called 'black' because we can’t see it.

Question 10

Why do we have day and night?

Accepted Answer

We have day and night because the Earth spins like a top. When your part of the Earth faces the Sun, it's day, and when it faces away, it's night.

Question 11

What is the moon?

Accepted Answer

The Moon is a big, rocky ball that orbits Earth. It shines at night because it reflects light from the Sun.

Question 12

Why is space so dark?

Accepted Answer

Space is dark because there's no air like on Earth to spread the Sun's light around. Only the objects like stars and planets that the sunlight hits directly appear bright.

Question 13

Can people live on other planets?

Accepted Answer

For now, humans can’t live on other planets because they don't have the air, water, and food we need to stay alive. Scientists are studying places like Mars to see if it might be possible in the future.

Question 14

What causes the seasons?

Accepted Answer

Seasons happen because the Earth is tilted as it travels around the Sun. This tilt makes different parts of Earth get more sun at different times of the year.

Question 15

How do astronauts travel in space?

Accepted Answer

Astronauts travel in space using spacecraft like rockets. These strong machines blast off from Earth and take astronauts to space stations or even the Moon.

Question 16

Why can't we breathe in space?

Accepted Answer

Space doesn't have air like we do on Earth, so there’s no oxygen to breathe. That’s why astronauts use special suits with oxygen tanks when they go outside their spacecraft.

Question 17

What is a comet?

Accepted Answer

A comet is a big ball of ice and dust that travels through space. When it gets close to the Sun, it heats up and looks like it has a glowing tail.

Question 18

What are constellations?

Accepted Answer

Constellations are patterns of stars that people have imagined to look like animals, people, or objects. They're like dots you can connect in the night sky to make a picture.

Question 19

Why are there no sounds in space?

Accepted Answer

Sound needs air or something to travel through, and space doesn't have air. That's why space is silent, even if there are big explosions or loud things happening.

Question 20

Why do astronauts seem to float in space?

Accepted Answer

Astronauts seem to float because they are in a place where Earth's gravity doesn't pull on them much. This makes them feel weightless, like they’re floating around.
