In the sky
A telescope is needed to see it: its apparent magnitude is 22.77. Visible from the whole Southern Hemisphere and north to latitude 12° N. South of latitude 12° S it never sets.
Through a telescope from Earth
Light's journey
The light you see tonight set out around the year 1732. At the speed of Voyager 1, the fastest craft leaving the Solar System (16.9 km per second), the trip would take 5.2 million years.
The Sun seen from there
From a planet around SONYC-ChaI-1, the Sun would look like a star of magnitude 9.60, in the direction where our sky has the constellation Cepheus. It would be invisible to the naked eye.
