In the sky
A telescope is needed to see it: its apparent magnitude is 14.72. Visible from the whole Southern Hemisphere and north to latitude 29° N. South of latitude 29° S it never sets. It stands highest at midnight in March, the best time to observe it.
Through a telescope from Earth
Light's journey
The light you see tonight set out 5,309 years ago. At that time the first farming villages were being founded; there was no writing yet. At the speed of Voyager 1, the fastest craft leaving the Solar System (16.9 km per second), the trip would take 94 million years.
The Sun seen from there
From a planet around OGLE2-TR-L9, the Sun would look like a star of magnitude 15.89, in the direction where our sky has the constellation Cepheus. It would be invisible to the naked eye.
