Using an american football field, a drone, some peas, a few chilli flakes, grapes, and some people playing footy, Mark Rober cleverly built what is probably the easiest to understand scale model of our solar system.
What’s even more interesting is that he included Planet Nine too in the scale model just to show how far away that mystery planet is, that's ten times the mass of Earth. If the Sun was a football and if Earth was the size of a head of a pin orbiting 23 metres away, Planet Nine (represented with a pea) would be 17.5 miles away from all of that.
The neatest trick in this scale model is Rober’s use of the drone. At distances that become much too far to see the football Sun, the drone gets shot straight up in the air to let us see exactly where the orbits of each planet is in relation to each other.
