In the sky
A telescope is needed to see it: its apparent magnitude is 24.27. 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 April, the best time to observe it.
Through a telescope from Earth
Light's journey
The light you see tonight set out around the year 1927. At the speed of Voyager 1, the fastest craft leaving the Solar System (16.9 km per second), the trip would take 1.8 million years.
The Sun seen from there
From a planet around ULAS J141756.22+133045.8, the Sun would look like a star of magnitude 7.24, in the direction where our sky has the constellation Cetus. It would be invisible to the naked eye.
