In the sky
A telescope is needed to see it: its apparent magnitude is 10.68. Visible from the whole Northern Hemisphere and south to latitude 54° S. North of latitude 54° N it never sets. It stands highest at midnight in June, the best time to observe it.
Through a telescope from Earth
Light's journey
The light you see tonight set out around the year 1273. At the speed of Voyager 1, the fastest craft leaving the Solar System (16.9 km per second), the trip would take 13 million years.
The Sun seen from there
From a planet around WASP-3, the Sun would look like a star of magnitude 11.65, in the direction where our sky has the constellation Columba. It would be invisible to the naked eye.
