It sure isn't to scale.
It’s an entirely accurate representation from the POV of the asteroid, or rather a point very near it, which artificially positions itself to keep the object in front of the earth. The stars are accurately depicted, but are hard to identify. I dld’d the “Eyes on the Solar Sytem” NASA app, and it let’s you run this view as well as many others, with various controls available. This includes the ability to turn on constellation labels. At the end, Tucana, Phoenix, and Grus are in view!
