Through a telescope from Earth
Light's journey
The light you see tonight set out around the year 166. At the speed of Voyager 1, the fastest craft leaving the Solar System (16.9 km per second), the trip would take 33 million years.
The Sun seen from there
From a planet around TOI-2049, the Sun would look like a star of magnitude 13.61, in the direction where our sky has the constellation Centaurus. It would be invisible to the naked eye.
