"The report also said that 12 'planetary mixers' that are a critical
component in Iran's ballistic missile program were attacked in the Israeli
air raids. "The planetary mixers are used to produce solid fuel for
long-range ballistic missiles, and their destruction severely damages
Iran's ability to renew its missile stockpile," the report explained."

Anyone know why it's called a planetary mixer?

Plane?
Planet?

What?

If Wikipedia is correct, it's a device used to mix round products,
ideal for mixing and kneading viscous pastes, in which the blades
each rotate on their own axes, and at the same time on a common axis,
thereby providing complete mixing in a very short timeframe.

Epicycles, isn't it?

I always loved the name "planetary gear" and how vivid the metaphor is.
Without knowing how the planetary mixer works, I would indeed assume it
must refer to epicyclic motion, as it is the case with the gears.

That's correct, but I have a different image in mind. A planetary mixer
models the motion of a planet with a single moon, each with circular
motions around its primary.

Two moons, actually, and counterrotating,
so not very planetary, really.
But the planet itsef does rotate on planerary gears,

I don't know the answer in this case, but typically a planetary mixer is
a stirrer whose axis moves in a circle around a central point. The
"planetary" refers to the mechanical linkage that moves the mixing
element around.

Try looking up "planetary food mixer".

Orrery. Mot a word we use very often, but it
combines planes and planets.

Those in the know may talk about a digital orrery.
Some of them are already museum pieces,
