In the sky
A telescope is needed to see it: its apparent magnitude is 23.51. Visible from the whole Northern Hemisphere and south to latitude 76° S. North of latitude 76° N it never sets. It stands highest at midnight in October, the best time to observe it.
Through a telescope from Earth
Light's journey
The light you see tonight set out around the year 1462. At the speed of Voyager 1, the fastest craft leaving the Solar System (16.9 km per second), the trip would take 10 million years.
The Sun seen from there
From a planet around ULAS J010531.78+142931.5, the Sun would look like a star of magnitude 11.02, in the direction where our sky has the constellation Virgo. It would be invisible to the naked eye.
