Under the 'has cleared its orbital neighborhood' and 'fuses hydrogen into helium' definitions, thanks to human activities Earth technically no longer qualifies as a planet but DOES count as a star.

Ceres does appear to be active in some form with cryovolcanoes, based on the 2015 Dawn mission.

I think focus ought to be more on what the qualifications are for the minor label. What does it mean to be minor?

Then It's say that it was a planet, though IANAPG.

There shouldn't be a 'minor' nomenclature, it's a contrivance. It's a planet, or not

Also, to reiterate, the issue being discussed is one of disqualification, and not what qualifies. Identifying a body as a planet or not should not be done based on the criteria of the crowded or not nature of the space around it.
