the solar system has eight major planets, and an unknown but probably quite large number of minor planets; the latter are mostly, but not invariably, icy. And there you go. I'm not sure we need to agonize about it much more than that.
Brilliant, Sir, although that succinct summary caused a few "but...umm" moments in quick succession over here.
I seem to often hear them using the term "world", as in "Pluto is a small icy world", or "the asteroids are mostly small, rocky or metallic worlds" or "Jupiter is a Jovian world." Is that common, or was it just Carl Sagan who had such a romantic outlook?
I never noticed this, so I scratched around a little and experienced another one of those moments. Before I discard my work for the day and get sucked into the internet black hole I am going to go with: "we can cope with having three capitals, so we can deal with this world word!" I suppose I can use my 'hackles test'. It will raise my hackles to hear of someone referring to Cape Town as the capital of South Africa. My hackles will stay down if they specified legislative
capital. So, the context would matter.
