In the sky
A telescope is needed to see it: its apparent magnitude is 9.72. Visible from the whole Northern Hemisphere and south to latitude 10° S. North of latitude 10° N it never sets.
Through a telescope from Earth
Light's journey
The light you see tonight set out around the year 1914. At the speed of Voyager 1, the fastest craft leaving the Solar System (16.9 km per second), the trip would take 2.0 million years.
The Sun seen from there
From a planet around GJ 4101, the Sun would look like a star of magnitude 7.50, in the direction where our sky has the constellation Mensa. It would be invisible to the naked eye.
