When a moon has a moon, it's a moonmoon

Moonmoons

Since moonmoons have yet to be discovered, they have yet to have an official name.

Of course, the obvious question would be: how would you call a moon's moon?

Astronomers Juna Kollmeier and Sean Raymond, from the Observatories of the Carnegie Institution of Washington and the University of Bordeaux, respectively, published a working paper Tuesday exploring the possibility that moons could have moons of their own, according to Gizmodo.

But when the famed NASA Hubble Telescope suggested at the beginning of October there may be evidence of a Neptune-sized moon in another star system circling the gas-planet Kepler-1625b, Kollmeier revved up her research. There should also be enough distance between the main moon and the planet it orbits. When moons are too close to their host planets, there would be a risk of losing their moonmoons due to tidal and gravitational forces from the planet, which would tear the moonmoon apart. Along with moonmoons, they could also be called submoons, moonitos, moonettes, or moooons.

If the sizes don't match up just right, the smaller moon would be ripped away from the larger moon and shot into space or toward the planet the moon was orbiting.

The Ministry of agriculture of Greece was forbidden to ride donkeys in Santorini people who weigh over a hundred kilograms. However, there is no telling how this new law will be enforced in Santorini and in other parts of Greece .

The researchers write, 'While many planet-moon systems are not dynamically able to host long-lived submoons, the absence of submoons around known moons and exomoons where submoons can survive provides important clues to the formation mechanisms and histories of these systems.

It is natural to ask, can submoons orbit moons?

But regardless of the name - or if they even exist at all - the idea of moonmoons alone is enough to raise thoughts skyward to the mysterious heavens and leave the chaos of Earth behind, even if just for a few moon-swooning moments. Theoretically need to satisfy the conditions of Titan and yapet Saturn, Callisto, Jupiter and even our own Moon. Except they don't. So we might have to wait a bit before we can validate the theory.

But other scientists are using the far more delightful term moonmoon, so that's what we're going to go for.

'Further studies of the potential formation mechanisms, long-term dynamical survival, and detectability of submoons is encouraged'.
