#3Yep, that little dot in the sea of infinity is our little blue marble. No one have ever been more than a pixel (EDIT: a couple hundred pixels) distant from it, and soon even that achievement would fade from living memory.

Well, we've been a bit farther away than a single pixel :) The moon is also visible in the photo (and appears to be closer to Earth than it actually is because the Moon-Earth-Saturn angle was not 90 degrees when Cassini took this picture).

#5It's a bit trippy to look at that picture, and realize that literally everything I know exists in that one little spec. It's cosmically humbling.

Earth in this image has a diameter of around 5 pixels. So each pixel here is around 2500 km (as diameter of earth is around 12700 km [1])
Farthest human has been is 400,000 km [2]. So the farthest we have ever been is around 160 pixels.

Ah, i see. I thought the Moon was unresolved within the dot, not the faint dot to the left. :(

And there is also this beauty with Earth visible: https://saturn.jpl.nasa.gov/resources/3315/

#9I know Cassini isn't really the point of this particular image, but was reading over the weekend about all of its accomplishments. It is quite amazing how much that one program has achieved - and if we eventually find life on Enceladus it will be just one more.

Does this pedantry really change the meaning of Artlav's statement?
