In the sky
A telescope is needed to see it: its apparent magnitude is 20.81. Visible from the whole Southern Hemisphere and north to latitude 74° N. South of latitude 74° S it never sets. It stands highest at midnight in December, the best time to observe it.
Through a telescope from Earth
Light's journey
The light you see tonight set out around the year 1974. At the speed of Voyager 1, the fastest craft leaving the Solar System (16.9 km per second), the trip would take 920 thousand years.
The Sun seen from there
From a planet around WISEA J064750.85-154616.4, the Sun would look like a star of magnitude 5.84, in the direction where our sky has the constellation Hercules. It would be visible to the naked eye.
