Study Examines If an Ancient Star Flyby Had Any Effect on Earth

Anton, I’ve been watching you for 10 years now. Ever since your old universe sandbox videos. I was a small kid then. Thank you man. (Edit) wow I’m so happy to know so many of us grew up with the “what the math” intro lol.

You guys need to check out "The Star" by HG Wells. A star roughly the same size of our Sun that wreaks absolute havoc while passing through our solar system. Written before 1900, it was a pioneer of "hard" sci fi because it observed Newtonian physics. (This was before Einstein and no one knew about Pluto yet)

It's becoming increasingly hard to avoid the idea that a large moon may be essential to a level of stability allowing complex life to develop.

I’ve watched about a 100 of your videos. This one blew my mind more than any other one! I had no idea other solar systems got this close this frequently. 😅

Gaia determined a potentially much more significant close stellar flyby 2.8 million years ago involving a yellow star comparable to the sun (HD 7977). It went deep into the Oort Cloud (estimates range from 0.06-0.49 light years) and should have been sending a load of comets our way by now. The lower end estimate is even enough to alter objects just past the Kuiper belt like Sedna.

I read somewhere that the journey of an object from the rim to reach the inner solar system would be around a million years..who knows what time delayed objects are incoming.

Don't forget that if another star passes through OUR Oort cloud, the other star will most likely have its own Oort cloud and we will pass through its Oort cloud. So millions of small objects will pass directly through the middle of our solar system.

Of interest: the star is now 22 light years away after only 70,000 years. When you consider that comets perturbed by this star are expect to take 2 million years to reach the inner solar system, the speed at which our star systems are moving apart must be pretty great, that speed is .03143% of the speed of light or 210,685 miles per hour or 339,142 kilometers per hour. The next star expected to fly by our sun is Gliese 710 in 1.29 million years. That seems a comfortable margin, as these things go.

The more fly-bys, the more stable the old standard model becomes? That is quite interesting.

So Planet X but it’s a star?
