Through a telescope from Earth
Light's journey
The light you see tonight set out around the year 1227. At the speed of Voyager 1, the fastest craft leaving the Solar System (16.9 km per second), the trip would take 14 million years.
The Sun seen from there
From a planet around 70 Aql, the Sun would look like a star of magnitude 11.78, in the direction where our sky has the constellation Hydra. It would be invisible to the naked eye.
Position, brightness and colour from the HYG / AT-HYG catalogue; temperature, luminosity, radius and mass are approximate values computed from these observations.
