In the sky
A telescope is needed to see it: its apparent magnitude is 9.49. Visible from the whole Northern Hemisphere and south to latitude 75° S. North of latitude 75° N it never sets. It stands highest at midnight in February, the best time to observe it.
Through a telescope from Earth
Light's journey
The light you see tonight set out around the year 1966. At the speed of Voyager 1, the fastest craft leaving the Solar System (16.9 km per second), the trip would take 1.1 million years.
The Sun seen from there
From a planet around GJ 1120B, the Sun would look like a star of magnitude 6.16, in the direction where our sky has the constellation Capricornus. It would be visible to the naked eye.
