In the sky
A telescope is needed to see it: its apparent magnitude is 10.86. Visible from the whole Northern Hemisphere and south to latitude 63° S. North of latitude 63° N it never sets. It stands highest at midnight in December, the best time to observe it.
Through a telescope from Earth
Light's journey
The light you see tonight set out around the year 1000. At the speed of Voyager 1, the fastest craft leaving the Solar System (16.9 km per second), the trip would take 18 million years.
The Sun seen from there
From a planet around HAT-P-56, the Sun would look like a star of magnitude 12.32, in the direction where our sky has the constellation Sagittarius. It would be invisible to the naked eye.
