Given that the closest star (sun excepted) is 4.3 light years away, and that the star with the highest relative velocity to the sun (Wolf 424) is 555 km/second (however a lot of stars have not had their velocity measured yet), this means that IF Wolf 424 was where Alpha Centauri is now, AND its speed was to take it perfectly towards us (instead of any other direction) it would still need 2300 years to get here, so, anytime soon it is not.

No. While asteroids, meteors and comets could surprise us, something as large and bright as a star would already be known about by astronomers. There are no stars that are any danger of entering our solar system.

The chances of a star entering our solar neighborhood are slim but our chances of being eliminated by a rogue asteroid or a comet is more likely.

No.
There is no star that is moving even vaguely in our general direction, and if there were it would be millions of years away at this time.
The answer about Wolf 424 is correct, but confusing. It is not where A. Centauri is, but much further away.

Anything is possible now.
The Movies : "Meteor" and "Deep Impact" foretells and warns us
of the imminent danger of a possible event that will alter history or annihilate mankind from the face of the earth.
At any given time, all the telescopes combined can only observe
3 % of the horizon.
