The computer program Gaia Sky, developed in Heidelberg, Germany, shows the Sky as measured with the Hipparcos and Gaia satellites (the Gaia measurement are based on the second Gaia catalogue, published on April 25, 2018). 

 Gaia measures the parallaxes (the apparent motion of the stars due to the annual movement of the Earth around the Sun and the finite distance of the stars) and the proper motions of the stars.

If parallaxes and proper motions were 100,000 times larger than in reality they would be easy to observe. With Gaia Sky we have simulated this. At the end of the video it is shown how the constellations change due to the motion of the star (accelerated by a trillion times compared to the real movement).
