In the sky
A telescope is needed to see it: its apparent magnitude is 10.08. Visible from the whole Southern Hemisphere and north to latitude 85° N. It stands highest at midnight in June, the best time to observe it.
Through a telescope from Earth
Light's journey
The light you see tonight set out around the year 1992. At the speed of Voyager 1, the fastest craft leaving the Solar System (16.9 km per second), the trip would take 605 thousand years.
The Sun seen from there
From a planet around Gl 654, the Sun would look like a star of magnitude 4.93, in the direction where our sky has the constellation Orion. It would be visible to the naked eye.
