A telescope is needed to see it: its apparent magnitude is 12.05. Visible from the whole Northern Hemisphere and south to latitude 84° S. It stands highest at midnight in May, the best time to observe it.
Through a telescope from Earth
Light's journey
The light you see tonight set out around the year 1376. At the speed of Voyager 1, the fastest craft leaving the Solar System (16.9 km per second), the trip would take 12 million years.
The Sun seen from there
From a planet around HAT-P-27, the Sun would look like a star of magnitude 11.33, in the direction where our sky has the constellation Eridanus. It would be invisible to the naked eye.
