In the sky
A telescope is needed to see it: its apparent magnitude is 13.69. Visible from the whole Northern Hemisphere and south to latitude 43° S. North of latitude 43° N it never sets. It stands highest at midnight in July, the best time to observe it.
Through a telescope from Earth
Light's journey
The light you see tonight set out around 894 BC. At the speed of Voyager 1, the fastest craft leaving the Solar System (16.9 km per second), the trip would take 52 million years.
The Sun seen from there
From a planet around Kepler-1620, the Sun would look like a star of magnitude 14.59, in the direction where our sky has the constellation Puppis. It would be invisible to the naked eye.
