3I Atlas with a speed of 60 km/s takes ~21,000 years from our Sun to the next star Proxima Centauri. That is a very small interstellar distance of 4.24 light years. While Atlas is the fastest thing we have ever discovered, its still slow as fuck. Only 0.02% light speed.
Sorry anon but if its a comet there are no aliens on board to clap our cheeks.
