In the sky

Through a telescope from Earth
Light's journey
The light you see tonight set out 24 thousand years ago. At that time Homo sapiens was spreading out of Africa; there was no farming yet. At the speed of Voyager 1, the fastest craft leaving the Solar System (16.9 km per second), the trip would take 422 million years.
The Sun seen from there
From a planet around KMT-2018-BLG-0748L, the Sun would look like a star of magnitude 19.15, in the direction where our sky has the constellation Auriga. It would be invisible to the naked eye.
