First, I would think " How the heck has no one noticed this in billions of years?" And secondly, I would think it's really weird. The moon HAVING moons???

I would think that would be an incredible discovery.

That would be nice, because in the night sky, we will have 2 or more bright objects and some will sometimes be seen and sometimes not.
Right now, either we see the moon in different phases or we don't see it at all. If there is a moon orbiting, then at times when the moon is seen in the night sky, there will be instances when there will be 2 bright objects all at the same time or at times only the original moon, because it it possible the other moon will be eclipsed.
But then, perish the hypothetical thought, since we know for a fact that our moon does not have a moon of its own.

incredibly unlikely... if it ever is observed it will be a very temporary phenomenon... what you are essentially looking for is a body that has NOT been trapped by the primary's gravity and WOULD be trapped by the moons? sooner or later its orbit will take it between the primary and the moon and then the primaries gravity would take over or at least disrupt the stable orbit around the moon. A 3rd body could be "inserted" into a stable orbit using the Lagrange or Trojan points but it would have to be tidally locked into place and stay in constant alignment AWAY from the primary

The moon has a large amount of gravity just like any other planetary body, so it wouldn't be too strange. Other planets have moons that have moons.
Plus, it could aquire an orbiting body from a recent event. Of course, as of now, it has no moons; you;re right in thinking that we would have noticed something by now, but that doesn't mean that the moon can't have a moon in the future.

If the Sun has planets orbiting it, and the planets have moons orbiting them, then why would moons orbiting moons be impossible? There is so much we do not know about the universe that anything could be possible.
Moons probably do have moons orbiting them but the sizes are so small that the moon's moons would eventually accrete into the main body.
Don't forget, also, that Asteroid Ida has its own satellite, Dactyl, so it does happen!

Well, moons can have moons... Some moons orbiting jupiter and saturn are actually quite large, and their gravity is large enough to attract other objects into their orbit. Thirdly, i think we would've noticed an object so near our earth, circling our own moon. We'd notice it even if it was the size of a small asteroid.

Hi,There is a reason that no moon in this solar system has no moons.Well what made you think that there could be moon for our moon.
The gravitational force of the earth is strong enough to keep moon orbitting it .So it anything ever orbitted around the moon then it would definitely be closer to earth for some time and then the gravitational force of earth would pull it apart.
SO LITERALLY THERE CANT BE A SATELLITE FOR A SATELLITE.

I don't think such an arrangement would be very stable. Earth's gravity would constantly tug at the moon's moon and eventually pull it out of its orbit and into orbit around Earth. There's a reason none of the dozens of sizable sattelites in the solar system have moons of their own.

Yes, that is exactly what I would think. Why had nobody noticed before and how unusual it would be.

I think that it would be really cool. I wonder what the name would be?
