In the sky
A telescope is needed to see it: its apparent magnitude is 12.35. Visible from the whole Northern Hemisphere and south to latitude 83° S. 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 the year 1991. At the speed of Voyager 1, the fastest craft leaving the Solar System (16.9 km per second), the trip would take 614 thousand years.
The Sun seen from there
From a planet around GJ 1236, the Sun would look like a star of magnitude 4.96, in the direction where our sky has the constellation Monoceros. It would be visible to the naked eye.
