I’m not sure if the average person on the street would know the terms Luna, Terra, Sol, and especially Astra.
Also, the biggest being Astra is a bit confusing. Sol is also a star.
Furthermore, unless you know they’re supposed to be ordered by size you can’t know which is best.
Corsa, Astra, Vectra and Omega would be better names.

I don't think these are as difficult as you're making them sound? I think the majority of people who will care what model they're using will know "lunar", "terrestrial", "solar", "astronomy" etc?
The average person isn't supposed to care, they won't be switching models to prompt for the best television for under $1000. But for professionals they should have some sort of understanding of these things.
