In the sky
A telescope is needed to see it: its apparent magnitude is 11.01. Visible from the whole Southern Hemisphere and north to latitude 51° N. South of latitude 51° S it never sets. It stands highest at midnight in May, the best time to observe it.
Through a telescope from Earth
Light's journey
The light you see tonight set out around the year 1984. At the speed of Voyager 1, the fastest craft leaving the Solar System (16.9 km per second), the trip would take 747 thousand years.
The Sun seen from there
From a planet around Gl 620.1B, the Sun would look like a star of magnitude 5.38, in the direction where our sky has the constellation Perseus. It would be visible to the naked eye.
