In the sky
A telescope is needed to see it: its apparent magnitude is 13.79. Visible from the whole Northern Hemisphere and south to latitude 72° S. North of latitude 72° 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 1889 BC. At the speed of Voyager 1, the fastest craft leaving the Solar System (16.9 km per second), the trip would take 69 million years.
The Sun seen from there
From a planet around GJ 3667, the Sun would look like a star of magnitude 15.23, in the direction where our sky has the constellation Aquarius. It would be invisible to the naked eye.
