Light's journey
The light you see tonight set out around 134 BC. At the speed of Voyager 1, the fastest craft leaving the Solar System (16.9 km per second), the trip would take 38 million years.
The Sun seen from there
From a planet around K2-258, the Sun would look like a star of magnitude 13.93, in the direction where our sky has the constellation Cetus. It would be invisible to the naked eye.
