Through a telescope from Earth
Light's journey
The light you see tonight set out around the year 504. At the speed of Voyager 1, the fastest craft leaving the Solar System (16.9 km per second), the trip would take 27 million years.
The Sun seen from there
From a planet around HIP 87099, the Sun would look like a star of magnitude 13.18, in the direction where our sky has the constellation Taurus. It would be invisible to the naked eye.
