In the sky
A telescope is needed to see it: its apparent magnitude is 9.82. Visible from the whole Northern Hemisphere and south to latitude 22° S. North of latitude 22° N 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 185. At the speed of Voyager 1, the fastest craft leaving the Solar System (16.9 km per second), the trip would take 33 million years.
The Sun seen from there
From a planet around Gl 854, the Sun would look like a star of magnitude 13.59, in the direction where our sky has the constellation Carina. It would be invisible to the naked eye.
