In the sky
A telescope is needed to see it: its apparent magnitude is 10.42. Visible from the whole Southern Hemisphere and north to latitude 15° N. South of latitude 15° S it never sets.
Through a telescope from Earth
Light's journey
The light you see tonight set out around the year 1998. At the speed of Voyager 1, the fastest craft leaving the Solar System (16.9 km per second), the trip would take 497 thousand years.
The Sun seen from there
From a planet around Gl 877, the Sun would look like a star of magnitude 4.50, in the direction where our sky has the constellation Draco. It would be visible to the naked eye.
