Through a telescope from Earth
Light's journey
The light you see tonight set out around the year 1581. At the speed of Voyager 1, the fastest craft leaving the Solar System (16.9 km per second), the trip would take 7.9 million years.
The Sun seen from there
From a planet around ITG 15 A, the Sun would look like a star of magnitude 10.50, in the direction where our sky has the constellation Scorpius. It would be invisible to the naked eye.
