In the sky
A telescope is needed to see it: its apparent magnitude is 14.85. Visible from the whole Northern Hemisphere and south to latitude 80° S. North of latitude 80° N it never sets. It stands highest at midnight in November, the best time to observe it.
Through a telescope from Earth
Light's journey
The light you see tonight set out around the year 1985. At the speed of Voyager 1, the fastest craft leaving the Solar System (16.9 km per second), the trip would take 728 thousand years.
The Sun seen from there
From a planet around GJ 1055, the Sun would look like a star of magnitude 5.33, in the direction where our sky has the constellation Libra. It would be visible to the naked eye.
