Through a telescope from Earth
Light's journey
The light you see tonight set out around the year 1986. At the speed of Voyager 1, the fastest craft leaving the Solar System (16.9 km per second), the trip would take 703 thousand years.
The Sun seen from there
From a planet around WISEP J004701.06+680352.1, the Sun would look like a star of magnitude 5.25, in the direction where our sky has the constellation Musca. It would be visible to the naked eye.
