What is the biggest thing you've ever built? Have you ever tried constructing a solar system model? Join us as we attempt building one to scale, to see just how big our solar system really is. Spoiler alert: it's mind-bogglingly, awe-inspiringly big.
To get a rough sense of the dimensions we are dealing with - Mars is a whopping 250,000,000 kilometres from the sun, and Jupiter is located a staggering 755,000,000 kilometres away. In fact, Jupiter is SO big, that it is thought that its gravitational pull bumped a space rock off its course some 66 million years ago. It is believed to have sent this comet hurtling towards Earth, killing all of the dinosaurs in the process.
