So, where exactly did that giant yellow orb in the sky we know as the sun originate?
Was the Sun Born in Messier 67? Or Somewhere Else?
Until recently, scientists suspected the sun came from Messier 67, a gigantic star cluster roughly 2.6 to 2.9 light years away from Earth. But new 3-D simulations appear to have thrown that theory into the dustbin of history, leaving the sun’s origin a mystery once more. Here’s more on the sun’s origin from National Geographic:
Stars like the sun typically form in clusters with other stars. Many clusters are spread out so that the stars drift apart, but others are denser, and gravity keeps their stars close together.
The sun now stands alone, so astronomers think our star—and its newborn solar system—was either ejected from its birth cluster or drifted away from its siblings about 4.5 billion years ago…
