In the sky
A telescope is needed to see it: its apparent magnitude is 13.97. Visible from the whole Southern Hemisphere and north to latitude 24° N. South of latitude 24° S it never sets. It stands highest at midnight in March, the best time to observe it.
Through a telescope from Earth
Light's journey
The light you see tonight set out around the year 1976. At the speed of Voyager 1, the fastest craft leaving the Solar System (16.9 km per second), the trip would take 890 thousand years.
The Sun seen from there
From a planet around GJ 2092, the Sun would look like a star of magnitude 5.77, in the direction where our sky has the constellation Cassiopeia. It would be visible to the naked eye.
