In the sky
A telescope is needed to see it: its apparent magnitude is 12.89. Visible from the whole Southern Hemisphere and north to latitude 54° N. South of latitude 54° S it never sets. It stands highest at midnight in August, the best time to observe it.

Light's journey
The light you see tonight set out around the year 202. At the speed of Voyager 1, the fastest craft leaving the Solar System (16.9 km per second), the trip would take 32 million years.
The Sun seen from there
From a planet around WASP-133, the Sun would look like a star of magnitude 13.57, in the direction where our sky has the constellation Lynx. It would be invisible to the naked eye.
