Class Quote by Alan Stern
“It used to be said that Pluto is a misfit. But now we know Earth is the misfit. This is the most populous class of planet in our solar system and we have never sent a mission to this class.”
About This Quote
The quote highlights that Earth, unlike the previously labeled 'misfit' Pluto, is actually the oddball among planets because it belongs to the most common planetary class—rocky, terrestrial worlds—yet humanity has never explored this class directly with a dedicated mission.
In simple terms: Earth is the overlooked common planet type.
Key Takeaway
We ignore the most typical planetary class.
