(Rephrase) Ok...The Earth and the moon (as a system) are big in comparison to other planet and moon systems..?

Just as you lump all responses with the ONE response that you quoted, I will also generalize and assume you didn't actually re-read your first question, after receiving such a negative comment about its structure? Did you for a moment say to yourself, "Gosh, maybe I could have worded that better?"

The Earth / Moon system NEARLY qualifies as a double planet, but "nearly" isn't really enough in astronomy, leading to misunderstandings, like the statement that "Jupiter is NEARLY large enough to be a brown dwarf star", when in fact, it is several orders of magnitude too light to ever be classed as one.

What we have is a large moon relative to its primary. That's all.

yes, it could almost be considered a double planet

the Moon is relatively large in comparison to the Earth.

Pluto and its largest moon, Charon, are sometimes treated as a binary system because the barycentre of their orbits does not lie within either body.[16] The IAU has yet to formalise a definition for binary dwarf planets, and until it passes such a ruling, they classify Charon as a moon of Pluto

But Pluto makes up for its small size by having the most gargantuan moon -- compared to its planet -- in the solar system.

The Moon is one of the most massive natural satellites relative to its primary (the planet it orbits). But the system itself has less mass than any of the gas giants.

The only planet/satellite system that is less massive than the Earth-Moon is the Mars-Phobos-Deimos system.

One could argue the Pluto-Charon-Hydra-Nix system is smaller as well, which it is, but definitions and terminologies make that one a semantical argument that I'm not going to consider.

Well, we haven't found any Earth-size planet systems yet. I guess the best quickest answer is Pluto and it's three known moons. And I know Pluto is no longer classified as a 'normal' planet, but it technically still a system.

NO
