Through a telescope from Earth
Light's journey
The light you see tonight set out around the year 642. At the speed of Voyager 1, the fastest craft leaving the Solar System (16.9 km per second), the trip would take 25 million years.
The Sun seen from there
From a planet around TOI-3807, the Sun would look like a star of magnitude 12.97, in the direction where our sky has the constellation Pavo. It would be invisible to the naked eye.
