Our solar system's planets are rarely shown to scale so, to rectify the problem, here are the 9 (Pluto's a planet dammit :)) in glorious color, complete with accurate rotation speeds keyed to each entity. :)
Enter planetary astronomer James O'Donoghue from the Japan Aerospace Exploration Agency (JAXA). He tweeted out a brief animation that starts off with the Ceres dwarf planet, and moves up through Solar System objects by size (including Earth), before closing by zooming out to take in the Sun.
Even if you know the relative size of everything in the Solar System, it's still quite a moment when Jupiter and the Sun swing into view – and you might never have realized quite how fast Jupiter spins relative to Earth either.
To scale works for me. :)
