Explaining the "Second Moon" that NASA discovered

We've seen astronomy news on Facebook saying that NASA has discovered a second moon, and that we'll have two moons in the sky.

Well, technically it could be true, but I don't think so. Besides, there are already crazy people taking images of two large moons in the sky (with AI), and people really think we're going to have two large moons in the sky.

Technically, it shouldn't even be called a moon, because astronomers and NASA call this little 18-meter piece of rock "2025 PN7," and it's a quasi-satellite because it's not bound by Earth's gravitational field; it orbits our sun.

So I think it's stupid to call a little 18-meter rock a "moon." A few years ago they had the stupid idea of ​​removing Pluto's "planet" category because it was too small, but now they want to call a tiny 18-meter little poo a "moon"?

Technically, it cannot be called the Moon because:

It is a small rock (18 meters).

It is not visible to the naked eye (by us) in the sky.

It does not orbit our planet; it orbits the sun.

It will disappear in 2083.

On social media, it has been nicknamed the "second moon," but that's a poetic title.

It is not visible (or seen, since it's a piece of rock) to the naked eye. Photos of two moons on the internet are manipulated.
