In the sky
A telescope is needed to see it: its apparent magnitude is 12.56. Visible from the whole Southern Hemisphere and north to latitude 77° N. South of latitude 77° S it never sets. It stands highest at midnight in January, the best time to observe it.

Light's journey
The light you see tonight set out around the year 255. At the speed of Voyager 1, the fastest craft leaving the Solar System (16.9 km per second), the trip would take 31 million years.
The Sun seen from there
From a planet around TOI-4794, the Sun would look like a star of magnitude 13.50, in the direction where our sky has the constellation Aquila. It would be invisible to the naked eye.
