In the sky
Too faint for the naked eye (magnitude 7.72); binoculars will find it. Visible from the whole Northern Hemisphere and south to latitude 36° S. North of latitude 36° N it never sets. It stands highest at midnight in July, the best time to observe it.
Through a telescope from Earth
Light's journey
The light you see tonight set out around the year 1658. At the speed of Voyager 1, the fastest craft leaving the Solar System (16.9 km per second), the trip would take 6.5 million years.
The Sun seen from there
From a planet around GJ 4134, the Sun would look like a star of magnitude 10.09, in the direction where our sky has the constellation Carina. It would be invisible to the naked eye.
Position, brightness and colour from the HYG / AT-HYG catalogue; temperature, luminosity, radius and mass are approximate values computed from these observations.
