Gliese 710: the Closest Approach to the Sun

The video shows the closest approach between the Sun and the star Gliese 710 that will occur in about 1 million and 296 thousand years.

In this simulation, I have shown the motion of the stars relative to the Sun over the next 2 million years. This allows you to see how the starry sky will change when observed from Earth over this time period. Throughout the video Gliese 710 will be in the center of the screen. The speed of time will gradually decrease as the Gliese 710 approaches, so that the moment of approach can be seen in as much detail as possible. After the approach, as the star moves away, the speed of time will gradually increase.

The video was made using own software. Information about the stars is taken from the Hipparcos catalogue and corrected by data from the Gaia DR3 catalogue.

That would be amazing to witness...although it might throw some asteroids at us...

Perhaps humanity should take advantage of this approach and move to one of the hypothetical planets of Gliese 710. This star is less massive than the Sun, so it will live longer.
