In the sky
A telescope is needed to see it: its apparent magnitude is 12.01. Visible from the whole Northern Hemisphere and south to latitude 37° S. North of latitude 37° N it never sets. It stands highest at midnight in April, the best time to observe it.

Light's journey
The light you see tonight set out around the year 656. At the speed of Voyager 1, the fastest craft leaving the Solar System (16.9 km per second), the trip would take 24 million years.
The Sun seen from there
From a planet around TOI-3894, the Sun would look like a star of magnitude 12.95, in the direction where our sky has the constellation Phoenix. It would be invisible to the naked eye.
