Welcome to our solar system! Although not accurate by magnitude, this representation is accurate by sidereal period. The sidereal period is the time it takes for a planet to make a full orbit, relative to the stars. On Earth, that's 365.25636 days. But on Pluto - which will forever be a planet in my 90s-child heart - it takes more than 248 years! In this representation one earth-year is equal to 10 seconds.
