Fun fact, we currently actually have 2 moons! 469219 Kamoʻoalewa is a quasi-satellite that was discovered in 2016 and has been following us for nearly a century. It's orbit (technically around the sun, not Earth) is stable enough that it will continue to follow Earth for millions of years before it decays and collides with Earth. It's about 100 meters in diameter, and the Chinese space agency is planning to land on it this year!

[Its] orbit (technically around the sun, not Earth)

I think that disqualifies it from being a moon.

Also, I would think that if anything other than a legitimate Earth orbit qualified, it would be the trojans at the Lagrange points before it would be any other sorts of Earth-crossing orbits. But I don't think even they qualify either.

Quasi-satellite is the technical name, which clarifies it's exact relationship to it's orbit between the Earth and Sun. Moon is not a technical name.

to it is orbit

(technically around the sun, not Earth)

So, ya know, not really a moon at all

While I was fact checking myself, I came across a list of dwarf planets. I previously assumed that there were only 2 in our solar system: Pluto and Ceres, but most definitions include 10! One of them is called Quaoar, which is half the size of Pluto and has rings!

Wow, 3,628,800 dwarf planets! I never knew there were so many out there!

Does that mean there are 518,400 space snow white planets in the solar system as well?

Blimey I had no idea! Thanks for sharing

It’s about 100 meters in diameter

That's about 1 football field for any Americans here.

Okay but how many A&W parking lots is that?

Another 469219 Kamoʻoalewa fun fact: We got a rocket on the way, it should be landing in July as part of the Tianwen-2 mission
