Scientists can know ‘100 years upfront’ if an asteroid will hit Earth

ANU astrophysicist and cosmologist Dr Brad Tucker says scientists can know as much as “100 years upfront” if an asteroid is on a collision direction with Earth.

“That’s the nice factor, those higher ones we all know, we all know maximum of them, the place they’re,” he informed Sky Information Australia.

“The one one that can come shut – shut being inside of 20 million kilometres – wouldn’t be till the tip, I consider 2090, perhaps 2100, that’s the one one we ever take a look at.”

Dr Tucker mentioned it’s most probably this asteroid won’t come just about the Earth when it passes.

He mentioned the smaller asteroids of fifty to 100 metres are of extra fear as scientists simplest know the positioning of a couple of of them, and the NASA DART challenge will assist to trace extra.

“This entire DART challenge is a part of a collection of tasks to higher get ready for this danger,” he mentioned.

“So now not simply are we able to shield in opposition to it, however are we able to to find them, are we able to catalogue them, are we able to monitor them, so we all know the place they’re.”
