After an quick look, I'll probably use most of the properties on your
synchronous and asynchronous types but co-type them with the "Orbit" type
and exclude the redundant properties. The type names could stay the same.  A
"Natural synchronous satellite" type would be co-typed with Orbit,
Synchronous satellite, and Natural satellite. I'll get into the nitty gritty
of properties and type names tomorrow.

I added an "Unknown origin satellite" type that reciprocates with "Orbited
body". I also added an "Earth satellite of unknown origin" topic. Would you
like that hypothetical satellite to have a synchronous or asynchronous orbit
around Earth?
