In the sky
A telescope is needed to see it: its apparent magnitude is 14.18. Visible from the whole Northern Hemisphere and south to latitude 8° S. North of latitude 8° N it never sets.
Through a telescope from Earth
Light's journey
The light you see tonight set out around the year 1984. At the speed of Voyager 1, the fastest craft leaving the Solar System (16.9 km per second), the trip would take 744 thousand years.
The Sun seen from there
From a planet around GJ 1220, the Sun would look like a star of magnitude 5.38, in the direction where our sky has the constellation Mensa. It would be visible to the naked eye.
