In the sky
A telescope is needed to see it: its apparent magnitude is 11.16. Visible from the whole Southern Hemisphere and north to latitude 59° N. South of latitude 59° S it never sets. It stands highest at midnight in September, the best time to observe it.
Through a telescope from Earth
Light's journey
The light you see tonight set out around the year 1967. At the speed of Voyager 1, the fastest craft leaving the Solar System (16.9 km per second), the trip would take 1.0 million years.
The Sun seen from there
From a planet around GJ 1009, the Sun would look like a star of magnitude 6.11, in the direction where our sky has the constellation Coma Berenices. It would be visible to the naked eye.
