In the sky
A telescope is needed to see it: its apparent magnitude is 12.65. Visible from the whole Southern Hemisphere and north to latitude 61° N. South of latitude 61° S it never sets. 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 1965. At the speed of Voyager 1, the fastest craft leaving the Solar System (16.9 km per second), the trip would take 1.1 million years.
The Sun seen from there
From a planet around GJ 4074, the Sun would look like a star of magnitude 6.20, in the direction where our sky has the constellation Gemini. It would be visible to the naked eye.
