In the sky
A telescope is needed to see it: its apparent magnitude is 15.50. Visible from the whole Northern Hemisphere and south to latitude 78° S. North of latitude 78° N it never sets. It stands highest at midnight in November, the best time to observe it.
Through a telescope from Earth
Light's journey
The light you see tonight set out around the year 1974. At the speed of Voyager 1, the fastest craft leaving the Solar System (16.9 km per second), the trip would take 927 thousand years.
The Sun seen from there
From a planet around GJ 3285, the Sun would look like a star of magnitude 5.85, in the direction where our sky has the constellation Ophiuchus. It would be visible to the naked eye.
