If you enjoyed this video, then let me know and i will start making current science news videos as well.
70,000 thousand years ago, an alien passed though our solar system. But not a little green man in a flying saucer, a big ball of burning gas. Astronomers have discovered that a real shooting star, came five times closer than our current nearest neighbor Proxima Centauri.No other star is known to have approached this close to us. The object, a red dwarf nicknamed Scholz’s star, cruised through the outer region of the solar system known as the Oort Cloud. The essentially failed star, wasn’t alone either, it was accompanied on its travels by an object known as a brown dwarf making it a binary star system. Astronomers discovered that the dim stars passed a very close 0.8 light years from the Sun, in comparison, our closest neighboring star Proxima Centauri is 4.2 light years away. Researchers observing the stars found that by recording the change in distance from the Sun to the stars and the star’s motion across the sky they could determine the trajectory of the ancient objects. By tracing its movements back in time, they found its close shave with the Sun occurred as recent as 70,000 years ago. The binary star system has a low mass and it was speeding by our solar system at the time which means that the effects caused on the Oort Cloud were very small. Currently Scholz star lies around 20 light years away in the constellation of Monoceros, so at least we haven’t got to worry about that happening again. Or maybe we have… Dr Mamajek of the University of Rochester estimates that a rogue star probably passes through the Oort Cloud every 100,000 years, or so. But he also suggests that an approach as close as the Scholz’s star is somewhat rarer, and is only estimated to occur once every nine million years. Until now, the top candidate for the closest predicted flyby of a star to the Sun was HIP 85605, which is predicted to come close to our Solar System in 240,000 to 470,000 years from now. So the Scholzs star really was to close for comfort and it may of even been visible to the naked eye all those years ago. So Let’s just hope that another one of these infiltrating stars, doesn’t head our way any time soon.
So theirs a story about a rogue star that if it had been around 1 light year closer, you wouldn’t be here and watching this video, so to celebrate hit the like button and if you haven’t already subscribe for much more to come.
