In the sky
A telescope is needed to see it: its apparent magnitude is 12.23. Visible from the whole Northern Hemisphere and south to latitude 81° S. It stands highest at midnight in April, the best time to observe it.
Through a telescope from Earth
Light's journey
The light you see tonight set out around the year 1984. At the speed of Voyager 1, the fastest craft leaving the Solar System (16.9 km per second), the trip would take 754 thousand years.
The Sun seen from there
From a planet around GJ 3846, the Sun would look like a star of magnitude 5.40, in the direction where our sky has the constellation Cetus. It would be visible to the naked eye.
