In the sky
A telescope is needed to see it: its apparent magnitude is 15.04. Visible from the whole Southern Hemisphere and north to latitude 78° N. South of latitude 78° S it never sets. It stands highest at midnight in April, the best time to observe it.
Through a telescope from Earth
Light's journey
The light you see tonight set out around 291 BC. At the speed of Voyager 1, the fastest craft leaving the Solar System (16.9 km per second), the trip would take 41 million years.
The Sun seen from there
From a planet around K2-127, the Sun would look like a star of magnitude 14.09, in the direction where our sky has the constellation Aries. It would be invisible to the naked eye.
