In the sky
A telescope is needed to see it: its apparent magnitude is 21.81. Visible from the whole Northern Hemisphere and south to latitude 33° S. North of latitude 33° N it never sets. It stands highest at midnight in February, the best time to observe it.
Through a telescope from Earth
Light's journey
The light you see tonight set out around the year 1805. At the speed of Voyager 1, the fastest craft leaving the Solar System (16.9 km per second), the trip would take 3.9 million years.
The Sun seen from there
From a planet around SDSS J094043.18+565049.1, the Sun would look like a star of magnitude 8.99, in the direction where our sky has the constellation Indus. It would be invisible to the naked eye.
