A telescope is needed to see it: its apparent magnitude is 14.80. Visible from the whole Southern Hemisphere and north to latitude 90° N. 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 710. At the speed of Voyager 1, the fastest craft leaving the Solar System (16.9 km per second), the trip would take 23 million years.
The Sun seen from there
From a planet around K2-8, the Sun would look like a star of magnitude 12.86, in the direction where our sky has the constellation Pisces. It would be invisible to the naked eye.
