If you are interested in scientifically accurate models in webgl, you may like this asteroid simulation, which models objects in our solar system in an astronomically accurate manner: http://asterank.com/3d/
I agree with you. I am calling them total bullshit on the scientific part.
They could at least try to put the Alpha Cassiopeiae and and Beta Cassiopeiae in the same "general" direction from the Sun. It would fool more people.
Distances seem to be correct but the coordinates aren't true at all.
Regardless, it looks beautiful. But it would be more beautiful if you could actually see their true locations. Without it, it is a just a game ui demo.
