Astronomical!: You Could Fit All The Planets In The Solar System In The Distance Between The Earth And Moon
This is a visualization of the average distance from earth to the moon, with all the planets of the solar system neatly fitting between the two with room to spare. Wow, it's weird to think the moon is actually that far away. Because when I'm outside looking at it at night it seems like it's RIGHT THERE. Thanks to Martin M, who agrees they should have still included Pluto for old time's sake.

How much water is on Earth?
The drawing above shows various blue spheres representing relative amounts of Earth's water in comparison to the size of the Earth. Are you surprised that these water spheres look so small? They are only small in relation to the size of the Earth. These images attempt to show three dimensions, so each sphere represents "volume." Overall, it shows that in comparison to the volume of the globe the amount of water on the planet is very small - and the oceans are only a "thin film" of water on the surface.
The largest sphere represents all of Earth's water, and its diameter is about 860 miles . It would have a volume of about 332,500,000 cubic miles (mi3) (1,386,000,000 cubic kilometers (km3). The smaller sphere represents the total amount of fresh water. The volume comes to about 2,551,100 mi3 (10,633,450 km3), of which 99 percent is groundwater, much of which is not accessible to humans. The diameter of this sphere is about 169.5 miles (272.8 kilometers).
