In the sky
A telescope is needed to see it: its apparent magnitude is 14.90. Visible from the whole Northern Hemisphere and south to latitude 83° S. 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 6,496 years ago. At that time the first farming villages were being founded; there was no writing yet. At the speed of Voyager 1, the fastest craft leaving the Solar System (16.9 km per second), the trip would take 115 million years.
The Sun seen from there
From a planet around GJ 2074, the Sun would look like a star of magnitude 16.33, in the direction where our sky has the constellation Aquarius. It would be invisible to the naked eye.
