A telescope is needed to see it: its apparent magnitude is 11.65. Visible from the whole Southern Hemisphere and north to latitude 13° N. South of latitude 13° S it never sets.
Through a telescope from Earth
Light's journey
The light you see tonight set out around the year 1990. At the speed of Voyager 1, the fastest craft leaving the Solar System (16.9 km per second), the trip would take 630 thousand years.
The Sun seen from there
From a planet around COCONUTS-2 A, the Sun would look like a star of magnitude 5.02, in the direction where our sky has the constellation Draco. It would be visible to the naked eye.
