Will a Milky Way and Andromeda collision kill all living creatures?
According to calculations by NASA physicists, the collision would occur in about 4 billion years.
It's estimated that the Milky Way has over 200 billion stars. And over 1 trillion in Andromeda.
But despite this, it's improbable any of the stars will collide with each other. That's because of the vast distance between stars. The average distance between stars in our galaxy is 5 light years - that's 30 trillion miles.
Although some stars may be thrown out of the galaxy.
