200,000 AD Constellations visible from Earth have been rendered unrecognisable

Proper motion - the continuous movement of celestial bodies due to changing orbits or the remaining effects of the Big Bang - has radically changed the view of the night sky from Earth. Stars naturally move at different velocities, depending on the manner in which a star formed from its original dust cloud. By 50,000 AD, constellations were beginning to be twisted and bent into new shapes and by 200,000 AD have become completely unrecognisable.This includes once famous groups of stars like the Big Dipper, Orion, Ursa Major, Perseus and Gemini. As a result of changes in Earth's axial orientation, Gamma Cephei, Iota Cephei and Vega have taken the position of the North Star.
