A telescope is needed to see it: its apparent magnitude is 12.86. Visible from the whole Northern Hemisphere and south to latitude 88° S. It stands highest at midnight in November, the best time to observe it.
Through a telescope from Earth
Light's journey
The light you see tonight set out around 101 BC. At the speed of Voyager 1, the fastest craft leaving the Solar System (16.9 km per second), the trip would take 38 million years.
The Sun seen from there
From a planet around HAT-P-64, the Sun would look like a star of magnitude 13.90, in the direction where our sky has the constellation Ophiuchus. It would be invisible to the naked eye.
