Our planet Earth’s radius is estimated to be about 6371 kilometers, but I doubt that this matters to you. Since an average person has nothing to compare these scales and distances to, they can hardly imagine them accurately. They're so broad that it's difficult to comprehend them. But let's give it a shot.
Consider our Earth to be the size of a tennis ball, and reducing all other dimensions to a specified scale, we get the following illustrative figures: the Sun would be about 1 km away from the tennis ball and would appear as a sphere with a diameter of a five-story house. Isn't it impressive? But that's not all: our galaxy's biggest stars have a diameter of around 2500 times that of the Sun. In our case, such a star will have the size of 3 diameters of the actual size of the Earth! Please keep in mind that the Earth is the size of a tennis ball! Nevertheless, even on such a small scale, the distance to the closest star is difficult to comprehend since it is around 220 thousand kilometers or roughly half of the distance to the Moon.
