In the sky
A telescope is needed to see it: its apparent magnitude is 13.50. Visible from the whole Southern Hemisphere and north to latitude 86° N. It stands highest at midnight in March, the best time to observe it.

Light's journey
The light you see tonight set out around the year 478. At the speed of Voyager 1, the fastest craft leaving the Solar System (16.9 km per second), the trip would take 27 million years.
The Sun seen from there
From a planet around GJ 3705, the Sun would look like a star of magnitude 13.21, in the direction where our sky has the constellation Pisces. It would be invisible to the naked eye.
