In the sky
A telescope is needed to see it: its apparent magnitude is 10.36. Visible from the whole Southern Hemisphere and north to latitude 39° N. South of latitude 39° S it never sets. It stands highest at midnight in August, the best time to observe it.
Through a telescope from Earth
Light's journey
The light you see tonight set out around the year 1978. At the speed of Voyager 1, the fastest craft leaving the Solar System (16.9 km per second), the trip would take 860 thousand years.
The Sun seen from there
From a planet around Gl 841A, the Sun would look like a star of magnitude 5.69, in the direction where our sky has the constellation Ursa Major. It would be visible to the naked eye.
