In the sky
A telescope is needed to see it: its apparent magnitude is 12.45. Visible from the whole Southern Hemisphere and north to latitude 76° N. South of latitude 76° 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 1988. At the speed of Voyager 1, the fastest craft leaving the Solar System (16.9 km per second), the trip would take 682 thousand years.
The Sun seen from there
From a planet around Gl 810A, the Sun would look like a star of magnitude 5.19, in the direction where our sky has the constellation Cancer. It would be visible to the naked eye.
