Scale comparison of the planets and the stars

These tiny and not so tiny balls show how enormous are the differences between different astronomical objects.

If Earth is a glass ball...

...then Jupiter is a football...

...and you'd fit into the Sun...

...and Sirius would crush you



An other series:



We have no actual photographs of other stars than our Sun that show surface details, because they're just too far away, so the rest is artwork based on what we do know about them - their color and size.



VV cephei is the largest star known - it's diameter is about 2000 times our sun's

And yet even it is just a tiny dot compared to the Milky Way itself


And an animation of the same objects

Hi there,
I'm an editor who works on astronomy textbooks. I absolutely love all of the scale photos you have on your site. Can you tell me what the original source of these photos is?
Many Thanks,
