It has taken 46 years to get 22.5 light hours away from Earth!
- sllabres 2y agoYes, this is why I always liked 'planet walks' like this [1] If you see Images the planets in the solar system, the solar system itself etc. are mostly not to scale. If you walk such path one get a bit of a feel how large everything is, I think especially if the plantes on the walk are to scale too. Even our solar system is mostly empty. And the distances to moon a microscopic. Walking such a path is is not the same, but a bit like [3] if one is patient (which is difficult on the internet) and doesn't scroll manually but only via the little "c" in the lower right corner, wich scrolls with light speed.
