Apparently they would be able to alter it's trajectory by getting a probe to fly with it at a certain point allowing it to miss. I think if I heard right it'll be hard to miss when it hopefully just flies by.

You know I was also thinking about how if we want to continue surviving as a race we'll have to eventually leave Earth but it's not as simple as finding a planet with a similar atmosphere to Earth as well as water. I mean they've found other planets in the habital zone of other solar systems that probably have oxygen and liquid water but they're all different sizes which means less and more gravity then that of Earth.
Mars for example, even if we could start settlements there only has 38% the gravity of Earth. Astronomers have found a couple dozen Earth like planets but some of them like Gliese 581 d are approximately 5.6 times the size of Earth which means gravity wise....well I've heard numbers ranging from 1.1-1.7 that of Earths surface gravity to 4 times that of Earths gravity. |
living on mars would be completely doable, it's just that the bones density of people that live there and don't excerise quite a bit would have a very hard time coming back to earth and getting on with things.
