In the sky
A telescope is needed to see it: its apparent magnitude is 10.93. Visible from the whole Northern Hemisphere and south to latitude 86° S. It stands highest at midnight in October, the best time to observe it.
Through a telescope from Earth
Light's journey
The light you see tonight set out around the year 1989. At the speed of Voyager 1, the fastest craft leaving the Solar System (16.9 km per second), the trip would take 655 thousand years.
The Sun seen from there
From a planet around Gl 70, the Sun would look like a star of magnitude 5.10, in the direction where our sky has the constellation Virgo. It would be visible to the naked eye.
