In the sky
A telescope is needed to see it: its apparent magnitude is 22.93. Visible from the whole Southern Hemisphere and north to latitude 61° N. South of latitude 61° 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 1918. At the speed of Voyager 1, the fastest craft leaving the Solar System (16.9 km per second), the trip would take 1.9 million years.
The Sun seen from there
From a planet around WISEA J045900.42-285338.3, the Sun would look like a star of magnitude 7.42, in the direction where our sky has the constellation Hercules. It would be invisible to the naked eye.
