35 Facts About Moonmoon

What is a Moonmoon?

The concept of a moonmoon is both intriguing and complex. Essentially, a moonmoon is a moon that orbits another moon. While this phenomenon hasn't been observed in our solar system, it's theoretically possible. Let's dive into some fascinating facts about moonmoons.

1. Definition and Terminology
   The term "moonmoon" is often used interchangeably with "submoon," "moonlet," and "moonito." These names reflect the internet's creative approach to naming an unnamed phenomenon, reminiscent of the "Boaty McBoatface" incident involving an Arctic research drone.

2. Historical Background
   The concept of moonmoons gained traction when an astronomer's son asked her if moons could have their own moons. This question, posed in 2014, prompted Juna Kollmeier, an astronomer at the Carnegie Institution Observatories, to dedicate her research to answering it.

3. Scientific Study
   Kollmeier and her colleague Sean Raymond, an astronomer at the University of Bordeaux, published a paper titled "Can Moons Have Moons?" on arXiv.org. This study explored the possibility of moonmoons and the conditions necessary for their existence.

Conditions for Moonmoon Existence

For moonmoons to exist, certain conditions must be met. These conditions involve the size of the moons and their orbital dynamics.

4. Size Requirements
   For a moonmoon to survive, it must be very small, with a diameter no larger than six miles (10 km). The host moon, on the other hand, needs to be large, with a diameter greater than 620 miles (1,000 km).

5. Orbital Conditions
   The moonmoon system requires a significant separation between the moonmoon, the host moon, and the planet they both orbit. If the moon is too small or too close to its host planet, it might lose its moonmoon to tidal dissipation, causing it to be shredded to pieces.

Potential Candidates in Our Solar System

While no moonmoons have been observed in our solar system, some moons could theoretically host them.

6. Potential Candidates
   Several moons in our solar system could hypothetically host mini-moons. These include Saturn's moons Titan and Iapetus, Jupiter's moon Callisto, and Earth's moon.
