In the sky
A telescope is needed to see it: its apparent magnitude is 14.40. Visible from the whole Northern Hemisphere and south to latitude 46° S. North of latitude 46° N it never sets. 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 2010. At the speed of Voyager 1, the fastest craft leaving the Solar System (16.9 km per second), the trip would take 284 thousand years.
The Sun seen from there
From a planet around Gl 412B, the Sun would look like a star of magnitude 3.28, in the direction where our sky has the constellation Grus. It would be visible to the naked eye.
