The future of the Orion constellation
This video reveals how our view of the Orion constellation will evolve over the next 450 000 years.
Amid a myriad of drifting stars, the shape of Orion as defined by its brightest stars is slowly rearranged into a new pattern as time goes by.
The portion of the sky depicted in the video measures 40 x 20º – as a comparison, the diameter of the full Moon in the sky is about half a degree.
The video is based on data from ESA’s Gaia and Hipparcos satellites, as well as additional information from ground-based observations.

Poor. At least time period should be named
Wait so Orien loses his head ~Meissa "the brightest in the sword" in how many years? Or is their another that goes out first?
정말 흥미롭게 잘 봤어요. 별들 하나하나마다 추적할 수 있는 비결이 궁금해요.
And now…
what is all of that stuff behind the stars, looks like an asteroid belt? Is it?
happening of events matching with my thoughts are the only connections i could figure out
how many stars are there in the video?
What was the timescale
