In the sky
Too faint for the naked eye (magnitude 8.28); binoculars will find it. Visible from the whole Northern Hemisphere and south to latitude 79° S. North of latitude 79° N it never sets. It stands highest at midnight in August, the best time to observe it.
Through a telescope from Earth
Light's journey
The light you see tonight set out around the year 1432. At the speed of Voyager 1, the fastest craft leaving the Solar System (16.9 km per second), the trip would take 11 million years.
The Sun seen from there
From a planet around MASCARA-1, the Sun would look like a star of magnitude 11.13, in the direction where our sky has the constellation Hydra. It would be invisible to the naked eye.
