In the sky
Too faint for the naked eye (magnitude 8.00); binoculars will find it. Visible from the whole Northern Hemisphere and south to latitude 85° S. It stands highest at midnight in June, the best time to observe it.
Through a telescope from Earth
Light's journey
The light you see tonight set out around the year 1392. At the speed of Voyager 1, the fastest craft leaving the Solar System (16.9 km per second), the trip would take 11 million years.
The Sun seen from there
From a planet around GJ 4035, the Sun would look like a star of magnitude 11.27, in the direction where our sky has the constellation Monoceros. 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.
