In the sky
A telescope is needed to see it: its apparent magnitude is 13.25. Visible from the whole Northern Hemisphere and south to latitude 42° S. North of latitude 42° 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 2000. At the speed of Voyager 1, the fastest craft leaving the Solar System (16.9 km per second), the trip would take 465 thousand years.
The Sun seen from there
From a planet around GJ 1151, the Sun would look like a star of magnitude 4.36, in the direction where our sky has the constellation Phoenix. It would be visible to the naked eye.
