Why does this mystery object come so close to earth's orbit?

This mystery object may be our first visitor from ...

If you look at the graph in the above word button it shows this mystery object as it roared through the solar system. But, look carefully at the graph too in how it looks like it was designed for this trajectory by intelligence.

I think the odds are better than 50-50 that this is a space probe from another part of our galaxy sent to check up on us from some other inhabited planet in our galaxy.
