Although planets are huge compared to our Earth, most illustrations show them deceptively large in proportion to astronomical distances.

One of my favourite pieces of information is that all the planets would fit between the Earth and the Moon.

Semi-major axis of the Earth – Moon distance: **384,399 km **

Diameter of Mercury: **4,879 km**

Diameter of Venus:**12,104 km**

Diameter of Mars: **6,779 km**

Diameter of Jupiter: **139,822 km**

Diameter of Saturn: **116,464 km**

Diameter of Uranus: **50,724km**

Diameter of Neptune: **49,244 km**

The total sum of the planets’ diameters is **380,016 **kilometers, having enough space to fit Pluto (**2,372 km**) and Ceres (**950 km**) as well.
