A telescope is needed to see it: its apparent magnitude is 13.02. Visible from the whole Northern Hemisphere and south to latitude 89° S. It stands highest at midnight in March, the best time to observe it.
Through a telescope from Earth
Light's journey
The light you see tonight set out around the year 1081. At the speed of Voyager 1, the fastest craft leaving the Solar System (16.9 km per second), the trip would take 17 million years.
The Sun seen from there
From a planet around K2-19, the Sun would look like a star of magnitude 12.14, in the direction where our sky has the constellation Pisces. It would be invisible to the naked eye.
