In the sky
A telescope is needed to see it: its apparent magnitude is 12.07. Visible from the whole Southern Hemisphere and north to latitude 64° N. South of latitude 64° S it never sets. It stands highest at midnight in May, the best time to observe it.
Through a telescope from Earth
Light's journey
The light you see tonight set out around 1728 BC. At the speed of Voyager 1, the fastest craft leaving the Solar System (16.9 km per second), the trip would take 67 million years.
The Sun seen from there
From a planet around Gl 563.2A, the Sun would look like a star of magnitude 15.13, in the direction where our sky has the constellation Aries. It would be invisible to the naked eye.
