In the sky
A telescope is needed to see it: its apparent magnitude is 13.78. Visible from the whole Northern Hemisphere and south to latitude 51° S. North of latitude 51° N it never sets. It stands highest at midnight in October, the best time to observe it.

Light's journey
The light you see tonight set out around 150 BC. At the speed of Voyager 1, the fastest craft leaving the Solar System (16.9 km per second), the trip would take 39 million years.
The Sun seen from there
From a planet around HAT-P-53, the Sun would look like a star of magnitude 13.95, in the direction where our sky has the constellation Centaurus. It would be invisible to the naked eye.
