Everyone knows that eight planets orbit the Sun. But thousands of other objects, including icy comets and football field-sized asteroids, are also zooming around our solar system. And some of them could be on a collision course with Earth. QUEST explores how these Near Earth Objects are being tracked and what scientists are saying should be done to prevent a deadly impact.

06:09 lmao earth is going to be hit by a giant penis!!

[enzomaidana]

I knowledge this is serious stuff, and that all of mankind should come together to find an answer to this theart, but, dont tell me that asteroid at 6:06 dont look like a penis.

The gravity tractor's advangage is that the asteroid can still be rotating.

But, weighing 1/10,000th or less than the asteroid, I don't think it would

be effective.

Soft-landing a rocket would be more effective but would need lots of fuel.

Low thrust ion engines that thrust for months at high efficiency.

If the asteroid rotated once a minute, the thruster could fire once a minute

for 15 seconds each time it faced the proper direction.

Lasers crater the surface, the vapor become reaction jets.
