Skullars distances in space with proper proportions :
1.
Earth is about 12800 km in diameter.
If Earth was a marble ( 1cm diameter ) lying in the goal of a soccer pitch, then the sun would be a big gym ball ( 109 cm in diameter ) lying in the other goal.
The distance of Earth-Sun is called an AU "astronomic Unit", about 150.000.000 km.
The distance Neptune-Sun is about 30 AU ( Neptune is the outer planet of the solar system ) which means that Neptune ( the size of a tomato while Earth is still a marble ) is about 3 kilometers away from our soccer pitch.
2.
The distance to the next star ( alpha centauri ) is about 4.4 lightyears, thats about 278256 A.U.
And THAT means, with marbles, tomatos and gymballs, the next star is 32608 kilometers away !
That means more than 3/4 of the length of earth's equator !
Well..... to allow you to ... zoom out in mind....
If the orbit of Neptune ( the tomatoe that flies around the gymball and is about 3 kilometers away, so its orbit is around 6km in diameter ) was only the size of a coin ( 1cm in diameter ), the next star would still be 43.3 meters away.
A coin in the center of the soccer pitch being neptune's orbit means : the next star is lying on the side line.
