In the sky
A telescope is needed to see it: its apparent magnitude is 10.65. Visible from the whole Northern Hemisphere and south to latitude 74° S. North of latitude 74° 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 1973. At the speed of Voyager 1, the fastest craft leaving the Solar System (16.9 km per second), the trip would take 936 thousand years.
The Sun seen from there
From a planet around Gl 844, the Sun would look like a star of magnitude 5.88, in the direction where our sky has the constellation Hydra. It would be visible to the naked eye.
