In the sky

Through a telescope from Earth
Light's journey
The light you see tonight set out 5,199 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 92 million years.
The Sun seen from there
From a planet around HIP 88876, the Sun would look like a star of magnitude 15.84, in the direction where our sky has the constellation Orion. It would be invisible to the naked eye.
