In the sky
A telescope is needed to see it: its apparent magnitude is 11.80. Visible from the whole Northern Hemisphere and south to latitude 58° S. North of latitude 58° 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 1985. At the speed of Voyager 1, the fastest craft leaving the Solar System (16.9 km per second), the trip would take 722 thousand years.
The Sun seen from there
From a planet around GJ 4098, the Sun would look like a star of magnitude 5.31, in the direction where our sky has the constellation Canis Major. It would be visible to the naked eye.
