In the sky
A telescope is needed to see it: its apparent magnitude is 13.45. Visible from the whole Southern Hemisphere and north to latitude 11° N. South of latitude 11° S it never sets.
Through a telescope from Earth
Light's journey
The light you see tonight set out around the year 1979. At the speed of Voyager 1, the fastest craft leaving the Solar System (16.9 km per second), the trip would take 829 thousand years.
The Sun seen from there
From a planet around GJ 3625, the Sun would look like a star of magnitude 5.61, in the direction where our sky has the constellation Cepheus. It would be visible to the naked eye.
