In the sky
A telescope is needed to see it: its apparent magnitude is 11.42. Visible from the whole Northern Hemisphere and south to latitude 50° S. North of latitude 50° N 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 1990. At the speed of Voyager 1, the fastest craft leaving the Solar System (16.9 km per second), the trip would take 630 thousand years.
The Sun seen from there
From a planet around GJ 4063, the Sun would look like a star of magnitude 5.02, in the direction where our sky has the constellation Columba. It would be visible to the naked eye.
