"This double asteroid system poses no threat to Earth."

Not until you smack into it with a spaceship it doesn't.

So, if NASA was to redirect the asteroid and it caused Planet X in an alternate galaxy to be destroyed would there be hell to pay when the Mother ship arrived to extract vengeance?

Will the mission director reluctantly say, “Missed it by THAT much!”

Specific impulse of 4,190 sec is remarkable.

The Space Shuttle main engine (SSME) specific impulse is 452 sec in vacuum.

The Apollo Command and Service Module SPS main engine had specific impulse of 314 seconds, but that was because they used hypergolic fuel with somewhat lower energy density than liquid hydrogen and liquid oxygen used by the SSME. That was because the SPS absolutely had to start.

This double asteroid system poses no threat to Earth currently but, after the experiment, all bets are off
