In the sky
A telescope is needed to see it: its apparent magnitude is 13.43. Visible from the whole Northern Hemisphere and south to latitude 71° S. North of latitude 71° 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 1934. At the speed of Voyager 1, the fastest craft leaving the Solar System (16.9 km per second), the trip would take 1.6 million years.
The Sun seen from there
From a planet around Gl 343, the Sun would look like a star of magnitude 7.08, in the direction where our sky has the constellation Capricornus. It would be invisible to the naked eye.
