The "Great Dying" (Permian-Triassic extinction): Occurred approximately 252 million years ago.
One Galactic Year (Orbit): It takes the Sun roughly 225 to 250 million years to complete one full revolution around the center of the Milky Way. 🌌
Therefore, since the Great Dying, the solar system has made approximately one complete orbit around the galaxy. The last time the Sun was in this specific location in the galaxy, the Permian extinction was occurring and dinosaurs were just beginning to evolve.
Key points regarding this timing:📌
The "One" Orbit Journey: The time passed (252 Ma) is almost exactly equal to one galactic year (225–250 Ma), meaning we have completed one full trip.⏳
Total Orbits: The Sun is about 4.6 billion years old and has completed roughly 20 full galactic orbits in its lifetime.😱
