Did you know? At any given moment, our planet is in close to the same spot in the Milky Way it was 250 million years ago. Due to the fact that We’re constantly moving because the earth is constantly rotating.
It’s also revolving around the sun, making a entire orbit once a year. Our sun, similarly, revolves around the Milky Way galaxy, taking our entire solar system with it.
It normally takes the sun roughly 225-250 million years to make a complete trip all over the galaxy, a period referred to as a “cosmic year.”
Today, that point in history correlates with the Permian-Triassic extinction, the most devastating event of our planet’s five mass extinction events, when 90% of underwater species and 70% of land species died out.
