I'm still hoping that one day they'll find my kind of planet...
Imagine a planet like Titan. It has a thick atmosphere, and the wind has sculpted the world. A gigantic amount of sand was left behind from this process, but in the meanwhile, the magnetic field was getting weaker and weaker... And then the atmosphere would be blown away by solar winds. All that would remain was sand. I call it an Atmosphereless Desert World. That is also my particular theory for Mars, a partial Atmosphereless Desert World, because it's atmosphere was not dense enough to create such a quantity of sand it ended up looking like a Dead Terra.
I'm sure I'll leave enough to see it, I just want them to classify it like that. I created it before whatever they are going to call the poor planet after all!
Why would you want to find another barren, lifeless rock?? Wouldn't it be more exciting to find a "jungle planet" or another planet that would have undeniable proof of life?
Besides, the word desert doesn't necessarily mean sand, it could be simply rock formations with very little to no water, or it could be areas covered with ice and snow, so your classification doesn't describe this particular planet you described, but rather a wide range of planets (not to say that this classification is wrong).
I would describe that planet as: Barren terrestrial world, with many products of erosion which is evidence to atmospheric and climatic activity in the past.
