Sorry to dash your hopes but when I say ‘star’, I mean the astronomical kind. Sadly, nobody has ejected Kanye West from Earth at that speed.
Astronomers have discovered a star travelling at 3,700,000 MPH (1,027 miles per second), which is about ten times faster than most stars move. They plotted its prior path and it appears to have come from the centre of the Milky Way, wherein lurks a supermassive black hole.
So how does a supermassive black hole eject a star when they’re best known for their insurmountable gravitational attraction?
Apparently it’s due to something called the Hills Mechanism, which sometimes kicks into action when a binary star system — consisting of two stars orbiting one another — gets close to a supermassive black hole.
If one of the stars in the binary system gets too close to the black hole, the ferocious gravity of the black hole will pull the star in. This takes energy away from the (three-body) system as a whole. However, thanks to the conservation of energy, the star that avoids the black hole will be given an energy equivalent to the infall velocity of the one that’s captured. The energy the surviving star receives is what results in its phenomenal speed.
The black hole ejected the star some 5 million years ago and it's travelling so fast it’ll escape our galaxy entirely within 100 million years. I look forward to seeing that happen. Astronomers have a had a pretty good look at this star as it’s fairly close to us now, only 29,000 light years (174,000,000,000,000 miles) away.
With absolutely no sense of drama, astronomers have called the star S5-HVS1. It should have been called something like Ergomighty the Ejector or whatever.
Things like this make me realise how fragile our little planet is in the galactic scheme of things.
