In the sky

Through a telescope from Earth
Light's journey
The light you see tonight set out around the year 1122. At the speed of Voyager 1, the fastest craft leaving the Solar System (16.9 km per second), the trip would take 16 million years.
The Sun seen from there
From a planet around 46 Leo, the Sun would look like a star of magnitude 12.04, in the direction where our sky has the constellation Aquarius. It would be invisible to the naked eye.
