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 498 thousand years.
The Sun seen from there
From a planet around CD Cet, the Sun would look like a star of magnitude 4.50, in the direction where our sky has the constellation Libra. It would be visible to the naked eye.
