Through a telescope from Earth
Light's journey
The light you see tonight set out 7,502 years ago. At that time the first farming villages were being founded; there was no writing yet. At the speed of Voyager 1, the fastest craft leaving the Solar System (16.9 km per second), the trip would take 133 million years.
The Sun seen from there
From a planet around MOA-2010-BLG-477L, the Sun would look like a star of magnitude 16.64, in the direction where our sky has the constellation Auriga. It would be invisible to the naked eye.
