In the sky
A telescope is needed to see it: its apparent magnitude is 15.50. Visible from the whole Northern Hemisphere and south to latitude 35° S. North of latitude 35° 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 1970. At the speed of Voyager 1, the fastest craft leaving the Solar System (16.9 km per second), the trip would take 986 thousand years.
The Sun seen from there
From a planet around GJ 1228, the Sun would look like a star of magnitude 5.99, in the direction where our sky has the constellation Carina. It would be visible to the naked eye.
