In the sky
A telescope is needed to see it: its apparent magnitude is 12.13. Visible from the whole Southern Hemisphere and north to latitude 75° N. South of latitude 75° S it never sets. It stands highest at midnight in July, the best time to observe it.
Through a telescope from Earth
Light's journey
The light you see tonight set out around the year 1970. At the speed of Voyager 1, the fastest craft leaving the Solar System (16.9 km per second), the trip would take 987 thousand years.
The Sun seen from there
From a planet around GJ 4077, the Sun would look like a star of magnitude 5.99, in the direction where our sky has the constellation Gemini. It would be visible to the naked eye.
