In the sky
A telescope is needed to see it: its apparent magnitude is 21.41. Visible from the whole Southern Hemisphere and north to latitude 48° N. South of latitude 48° S it never sets. It stands highest at midnight in July, the best time to observe it.
Through a telescope from Earth
Light's journey
The light you see tonight set out around the year 1861. At the speed of Voyager 1, the fastest craft leaving the Solar System (16.9 km per second), the trip would take 2.9 million years.
The Sun seen from there
From a planet around WISEA J203751.31-421645.2, the Sun would look like a star of magnitude 8.35, in the direction where our sky has the constellation Lynx. It would be invisible to the naked eye.
