A telescope is needed to see it: its apparent magnitude is 22.27. Visible from the whole Southern Hemisphere and north to latitude 89° N. 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 1664. At the speed of Voyager 1, the fastest craft leaving the Solar System (16.9 km per second), the trip would take 6.4 million years.
The Sun seen from there
From a planet around SDSS J094140.65-003215.8, the Sun would look like a star of magnitude 10.06, in the direction where our sky has the constellation Aquarius. It would be invisible to the naked eye.
