Here are some idioms about celestial bodies for you to check out.
sun expressions
Let’s kick things off with idioms about our glorious sun. The sun is that great big yellow hot ball in the sky that rises in the morning and sets at night.
We call it ‘the sun’ (using the definite article) as it is unique, there is only one sun.
Did you know the word ‘sun’ is pronounced in exactly the same way as the word ‘son’ (your male child). They are spelt differently, have a different meaning but pronounced the same, they are what we call homophones.

Now see if you can answer these questions. You can even leave your answers in the comments box at the end of the page if you like.
- Who was the last person you told to stick something where the sun doesn’t shine?

- What time do you rise and shine?

Tell me something you did many moons ago?
Do you often eat at a restaurant or only once in a blue moon?
star expressions
Stars are those twinkly luminous bodies that we see alongside the moon in the night sky. A picture of a star is typically drawn with 5 points.
Did you know that ‘star’ can also be used as an adjective to describe people? A star can be:
- A famous person e.g. I want to be a Hollywood star.
- Someone who has done something helpful for another person e.g. Martin was an absolute star, he came out in the pouring rain to help me change my tyre
- A brave person e.g. Mindy was a star, she didn’t cry once during her jabs.
