Through a telescope from Earth
Light's journey
The light you see tonight set out around 1367 BC. At the speed of Voyager 1, the fastest craft leaving the Solar System (16.9 km per second), the trip would take 60 million years.
The Sun seen from there
From a planet around AT2021ueyL, the Sun would look like a star of magnitude 14.92, in the direction where our sky has the constellation Antlia. It would be invisible to the naked eye.
