The scale of things
Here is a stunning computer-generated illustration of the planets in our solar system, our sun, and a handful of other stars that exist in our galaxy.
Just reading (for example) that the Earth’s diameter is 12756 km and Jupiter’s diameter is 142984 km fails to really make you appreciate the relative size of these things. It’s only when you place them all side by side and zoom out that you are fully able to realise the grand scale of it all.
Warning: watching this video may make you feel very, very small…
