In the sky
A telescope is needed to see it: its apparent magnitude is 10.97. Visible from the whole Northern Hemisphere and south to latitude 66° S. North of latitude 66° N it never sets. It stands highest at midnight in September, the best time to observe it.
Through a telescope from Earth
Light's journey
The light you see tonight set out around the year 1883. At the speed of Voyager 1, the fastest craft leaving the Solar System (16.9 km per second), the trip would take 2.5 million years.
The Sun seen from there
From a planet around GJ 3048, the Sun would look like a star of magnitude 8.04, in the direction where our sky has the constellation Hydra. It would be invisible to the naked eye.
