If your worried about big celestial bodies hitting us - fear this monster if it ever came our way its in this galaxy:-

On the Wiki page you can see its size in comparison to our own Sun.
The shear size of Cepheus's in comparison to our own Sun is incredible, like a grain of sand compared to a football. But if the Earth does survive the Andromeda event, we can look forward to our own Sun expanding into a red giant, apparently Mercury and Venus will be engulfed and the Earth rendered uninhabitable due to the extreme heat, but we have some time yet, about 6 billion years.
