I want to assert that "sexy Object" ideas need to be understood.
Planets are seen by observatories when the star is actually showing a limb dimming.
We know this is true. Ceres is planet then asteroid somewhat on size somewhat on the idea of a sexy object. Planets were important in the 1800's, so Ceres was a planet. Pluto similarly.
You all know of better examples.
Obvious, earth is center then not.
Sun is full of carbon then other elements.
