Sun is very big. It looks much smaller because it’s very far.
In reality if we diminish Earth to the size of a grain of sugar (you can take anything that 1 mm in diameter – a small stone or a crumb of bread) then Sun is gonna be this big (show anything that 10 cm in diameter – ball for example).
Then put a 10 cm ball on the ground and make 5 big steps – 5 meters – and put a grain of sugar on the ground. And say – this is Mercury – the nearest planet to the Sun.
Make another 5 steps, put another grain on the ground and say – this is Venus.
Repeat again. This is Earth.
Repeat again. This is Mars.
There’re another planets in the Solar system – I will tell you about them later.
DETAILS:
Every step between Sun, Mercury, Venus, Earth and Mars is 50 million kilometers. So it’s easy to remember.
The size of Sun (10 cm ball) is 1 million kilometers in diameter.
The size of Earth (1 mm crumb) is 12000 kilometers in diameter.
The sizes of Mercury, Mars, Earth and Venus don’t differ much – so you can use 1 mm crumb to represent all of them.
All sizes and distances are scaled properly this way.
