In the sky
A telescope is needed to see it: its apparent magnitude is 12.99. Visible from the whole Southern Hemisphere and north to latitude 71° N. South of latitude 71° 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 45 BC. At the speed of Voyager 1, the fastest craft leaving the Solar System (16.9 km per second), the trip would take 37 million years.
The Sun seen from there
From a planet around TOI-6420, the Sun would look like a star of magnitude 13.84, in the direction where our sky has the constellation Delphinus. It would be invisible to the naked eye.
