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?
🙁 it’s my favourite constellation
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
