A bit off topic, but can we start straight up catching these in Low Earth Orbit? What's the hard part here? Detecting them before they're close or getting a earth orbiting satellite to the precise right place at the right time?

Detecting, then catching a small object, in space, traveling at 10-20 thousand kilometers per hour.

Much easier to go out to an asteroid. https://en.wikipedia.org/wiki/OSIRIS-REx

Even faster than that! Meteors have a relative velocity between 11 and 71 km/s (40,000-255,000 kph). Anything faster than that would be interstellar, which is uncommon but not unheard of.

Pedantically, the lower limit of velocity relative to low-orbiting satellites is around 3 km/s. The 11 - 71 km/s figure is relative to the ground.

Catch it with what?

A big net, or a gigantic baseball glove.

Give kerbal space program a shot. It teaches you hard lessons about this and others.
