Cosmic.

A cosmic year is 225-250 million Earth years. That’s how long ago the Triassic period was, when the first dinosaurs appeared and the world was made up of one single super-continent called Pangaea!

Soooo, that means that our Solar System has orbitted the Milky Way ONCE since those prehistoric creatures roamed the land, sea and sky.

Think about it.
