In the sky
A telescope is needed to see it: its apparent magnitude is 14.16. Visible from the whole Southern Hemisphere and north to latitude 28° N. South of latitude 28° S it never sets. It stands highest at midnight in July, the best time to observe it.
Through a telescope from Earth
Light's journey
The light you see tonight set out around 926 BC. At the speed of Voyager 1, the fastest craft leaving the Solar System (16.9 km per second), the trip would take 52 million years.
The Sun seen from there
From a planet around TOI-3278, the Sun would look like a star of magnitude 14.61, in the direction where our sky has the constellation Camelopardalis. It would be invisible to the naked eye.
