Our Sun is inconstant. Through time, the brightest Shine on our firmament will grow more active than nowadays. Though, by human standarts it is yet a far way to go, we can be sure, that the future generations will be forced to leave Earth.
The Solar System's planets are named after ancient gods. There's so much antique in it. Even now I can imagine how children will regard the Solar System map in their history textbooks, just like we do with the history of the Roman Empire. They will see planets, devoured by the nuclear oven of the fading Sun. Our stellar system will also seem some mythical place to them.
The new sky will reveal new guiding lines, drawn by the light labyrinths, left by the stars, gone long ago. There's a try to imagine new star maps, that will exist in the remote future world.
