Moons Can Have Moons and They’re Called Moonmoons!

Scientists are exploring the possibility of a smaller moon going around a larger moon, and there is a truly adorable name being considered which is moonmoon.

No known moons have a moonmoon, but Sean Raymond and Juna Kollmeier, the astronomers working on the paper titled "Can Moons Have Moons?" argue that the existence of such a moon is possible given the right conditions.

For instance, the moonmoon shouldn't be too small or too close to the host planet.

Those factors could result in the destabilisation of its orbit due to tidal forces and consequently cause the moonmoon to crash into host planets or eventually be removed. Theoretically, any of Saturn's moons (Titan and Iapetus), Jupiter's moon Callisto or even our own moon could have a moonmoon, the astronomers wrote.

The International Astronomical Union will decide on its final name but internet users are already having fun with "moonmoon."
