In the sky

Through a telescope from Earth
Light's journey
The light you see tonight set out around the year 1300. At the speed of Voyager 1, the fastest craft leaving the Solar System (16.9 km per second), the trip would take 13 million years.
The Sun seen from there
From a planet around 54 Ari, the Sun would look like a star of magnitude 11.57, in the direction where our sky has the constellation Libra. It would be invisible to the naked eye.
