They’re always coming through.

The solar system is an interstellar highway.

Chariots Of The Gods, man.

But seriously, why would interstellar objects come towards our solar system?

It seems strange. Does gravity do that?

If there’s two within ten years then there has to be a veritable swarm of these things traveling between the stars - is that right or wrong?

A very rough calculation would suggested that the cylinder that goes from our solar system to Proxima Centauri contains 5000 similarly sized objects moving at the same speed:

1 object crossing the solar system plane every 5 years at 60km/s

Proxima Centauri is approximately 5 light years away

there are `speed of light / 60km/s` objects in the cylinder.
