Through a telescope from Earth
Light's journey
The light you see tonight set out around 1692 BC. At the speed of Voyager 1, the fastest craft leaving the Solar System (16.9 km per second), the trip would take 66 million years.
The Sun seen from there
From a planet around HATS-15, the Sun would look like a star of magnitude 15.11, in the direction where our sky has the constellation Cancer. It would be invisible to the naked eye.
