    not to worry
    I wouldn’t worry about it. Considering the age of the solar system, just above every asteroid is likely to have established orbits that pointedly miss the Terra / Luna dual planetary system. Most all those that could hit, already have. The dual planetary system and Terra’s magnetic field are good fall back defenses, as they work to deflect oncoming solid bodies.

    There’s always the possibility of a stray rock hitting Terra, of course. With the technology and resources we already have, there’s no excuse for not implementing an early warning system.

      Yep, and that chance is increasing. Our solar system moves “up” and “down” through the galaxy as it orbits. Every 65 million years we move through the most densely populated part of our region of the galaxy. The chances of an extinction-creating (eh, there’s a concept) impact increase during that time. It’s been about 65 million years sice the last event. This planet has been lucky on some occasions, but the list of massive extinction events and the time between them is somewhat compelling. Have a look
