Tasty Niblets

Roundabout

Though the sun was born 4.6 billion years ago, such is its distance from the Milky Way's galactic center (roughly, 26,000 light-years!) that it has only orbited it around 27 times since then!!

That means the last time we were roughly at the spot in the aforementioned orbit, the first terrestrial dinossaurs were starting to take their first steps here on Earth, during the mid-to-late Triassic period - - some astonishingly distant 230 million years ago!
