The Sun is the star at the centre of our solar system.
The nine planets orbit the sun.
Here is a useful mnemonic to help remember their order:
My Very Easy Method Just Shows Us the Names of Planets.

But what do we know about the Sun?
The Sun is 150 million kilometres away from us.
It has a massive diameter of 1,393,000 km.
Our Sun was probably formed from a large cloud of gas about 5,000 million years ago.

The moon orbits the Earth...

...as the Earth orbits the Sun.

As the Earth orbits around the Sun, it also spins on its own axis; which is tipped, like a globe’s.
![Page 10: Earth GB](https://reader035.vdocument.in/reader035/viewer/2022062705/556415fcd8b42a080c8b560a/html5/thumbnails/10.jpg)
At any time, half of the Earth faces the sun and therefore receives light.
The other half faces away from the Sun, and so receives very little light.
This part is in night.
This part is in day.

What causes the Earth’s seasons?
As the Earth orbits the Sun, when its axis tips towards the Sun, the weather gets warmer. When it tips away, the weather gets colder, causing the Earth’s seasons.

The Earth rotates on its axis at c 900 miles an hour! As it rotates, the Earth is
also orbiting the Sun at a speed of c 67,500 miles an hour!
But, don’t worry! Thanks to the Earth’s gravity and atmosphere, we won’t fall off.

So, when the Sun ‘rises’ in Great Britain, on the other side of the world, it’s about to ‘set’.

Now, with your partner, discuss these ideas about the moon:
I think the moon is a light source?
I think it keeps
changing shape?
It’s some
sort of a cycle!
![Page 16: Earth GB](https://reader035.vdocument.in/reader035/viewer/2022062705/556415fcd8b42a080c8b560a/html5/thumbnails/16.jpg)
Earth
moon
Why does the moon appear to change shape?
It takes the moon 28 days to orbit the Earth. For 27 days out of this cycle, the Sun cannot shine
on the whole of the surface, facing the Earth. The light from the Sun can only shine on the whole
surface for one night in each cycle: a full moon. On one night, no light from the Sun can reach the
moon at all: a new moon.

It takes 24 hours.
It turns anti-clockwise.
Do you know...
It takes 365¼ days.
It turns anti-clockwise.
how long it takes the Earth to spin round once?
which direction the Earth turns?
how long it takes the Earth to orbit the Sun once?
which direction the Earth orbits the sun?

Did you know?
One day on Venus lasts 117 Earth days.
Jupiter whips around in just 9 hours and 57 minutes.
One day on Mars is about the same as one day on Earth.

Now, explain to your partner:
How long does it take for the Earth to turn once?
Why does the Sun appear to rise and set?
Why, if is it day in New Zealand, it is night in England?
Why does the moon appear to change shape?
In which direction does the Earth spin on its axis?
In which direction does the Earth orbit the Sun?
