In the sky
A telescope is needed to see it: its apparent magnitude is 9.90. Visible from the whole Southern Hemisphere and north to latitude 36° N. South of latitude 36° 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 1981. At the speed of Voyager 1, the fastest craft leaving the Solar System (16.9 km per second), the trip would take 793 thousand years.
The Sun seen from there
From a planet around Gl 853B, the Sun would look like a star of magnitude 5.51, in the direction where our sky has the constellation Ursa Major. It would be visible to the naked eye.
