In the sky
A telescope is needed to see it: its apparent magnitude is 11.91. Visible from the whole Southern Hemisphere and north to latitude 12° N. South of latitude 12° S it never sets.
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 921 thousand years.
The Sun seen from there
From a planet around GJ 1077, the Sun would look like a star of magnitude 5.84, in the direction where our sky has the constellation Ursa Minor. It would be visible to the naked eye.
