Here are 5 short ways to say it:
- Stars come in different sizes and colours. Constellations are pictures made by joining them.
- Some stars are big or small and have different colours. When you connect them you see constellations.
- Stars vary in size and colour; join them and you get constellations.
- Stars look different, and patterns of joined stars are called constellations.
- Stars can be many sizes and colours — constellations are the pictures they make together.
