Alien Star cut through our Solar System some 70,000 years ago
Feeling pretty fucking safe, ain’t you. But you shouldn’t, you fucks. You can be sitting around, and little do you know, alien stars are whizzing through the Oort Cloud.
An alien star passed through our Solar System just 70,000 years ago, astronomers have discovered.
No other star is known to have approached this close to us.
An international team of researchers says it came five times closer than our current nearest neighbour – Proxima Centauri.
The object, a red dwarf known as Scholz’s star, cruised through the outer reaches of the Solar System – a region known as the Oort Cloud.
Scholz’s star was not alone; it was accompanied on its travels by an object known as a brown dwarf. These are essentially failed stars that lacked the necessary mass to get fusion going in their cores.
The findings are published in Astrophysical Journal Letters.
Observations of the dim star’s trajectory suggest that 70,000 years ago this cosmic infiltrator passed within 0.8 light years of the Sun. By comparison, Proxima Centauri is 4.2 light years away.
In the paper, astronomers led by Eric Mamajek at the University of Rochester, New York, say they are 98% certain that Scholz’s star travelled through what is known as the “outer Oort Cloud” – a region at the edge of the Solar System filled with trillions of comets a mile or more across.
This region is like a spherical shell around the Solar System and may extend out to as much as 100,000 Astronomical Units, or AU (one AU is the distance between the Earth and the Sun).
The Oort Cloud is thought to give rise to long-period comets that can swing past the Sun when their orbits are disturbed.
So fucking sick. Oh space! Even if it means you end up eradicating us, you’re so totally wizard.
