With 30 years lead time, I'm not going to worry about it. If we are ever capable of deflecting an asteroid, 25 years from now is the time to worry.
For now, I'm going to think that this could be a good deal.....as in resources coming within easy reach just about the time we'll be ready to take advantage of it.
Or more accurately, 24 years from now. That's when this asteroid is set to approach close enough for the Earth's gravity to possibly alter its trajectory enough to hit on the pass in 2036 - if it goes through a 'keyhole' in space about 641m wide.
Well, we are probably more likely to be able to change the course of a 3000 foot asteroid than we are to control the earth's weather.
Some asteroids have not been detected until they have passed earth. Just last year one missed us, and came very close. It was not detected until it had actually passed us.
I always get a kick out of people laughing this off, thinking it's all nonsense.
But look no further than the lunar surface and the surface of other planets and moons in our solar system. Thousands of those lunar and planetary impacts are massive. Even with our atmosphere, many large objects can easily penetrate and cause a cataclysmic event.
It's only a matter of time, until earth sustains a massive strike. It will be interesting to see how so called "modern" man reacts prior to impact, and after.
In 2025, land a couple nuclear-powered ion rockets on the surface and slowly push the asteroid into a different orbit.
